 - E2a1+) [RECOMMENDATION] If a judge finds a submitted solution that does not appear to have information to identify the attempt, they should check both sides of the paper.
 - E2b+) [CLARIFICATION] A competitor may choose to stop an attempt early by handing in a solution before the time limit.
 - E2c+) [CLARIFICATION] Although the judge may provide a standard sheet for competitors to submit solutions, a competitor may submit a solution on a different piece of paper. (Note that the piece of paper must come from the judge, according to [Regulation E3a](regulations:regulation:E3a).)
-- E2c1++) [ADDITION] If the competitor forgot to write information to identify the attempt on their intended solution paper, they are permitted to add it in front of a judge after the time limit. In this case, the competitor must ask the judge while submitting their solution and then immediately write information to identify the attempt (without making other changes) under direct supervision of the judge. Once a competitor has finished submitting their solution (e.g. placing it in the judge's hands and allowing the judge to move on to the next competitor, placing it on the judge's table and walking away), they are not permitted to add any information. If the competitor writes anything after the time limit but before asking the judge, the attempt remains disqualified (DNF).
+- E2c1+) [EXPLANATION] A competition registrant ID is an identifier (e.g. a number) assigned to a competitor for the competition. Some competitions use this to keep track of score sheets and enter results.
 - E2c1+++) [EXPLANATION] The competitor is not required to write the competition name, round, and/or attempt number on their submitted paper, but may wish to do so in order to help the organization team keep track of submitted solutions.
-- E2c1++++) [ADDITION] If a judge finds a submitted solution without information to identify the attempt (e.g. while grading the attempt), they should find out the competitor who wrote the solution in order to assign them a DNF (rather than DNS). Note that the competitor must not be allowed to write information to identify the attempt at this point, so they must receive a DNF result.
 - E2c2+) [EXAMPLE] Examples that are not considered a single unambiguous move sequence: multiple solution sequences without exactly one clearly indicated solution, a solution with ambiguous symbols (e.g. a letter that looks similar to "B" and "R" but is not clearly one or the other), a solution with stars or arrows indicating moves to be performed out of written order (e.g. "insertions" that are not written in-line with the rest of the move sequence, "pre-moves" that are not incorporated into the move sequence using valid notation), a move sequence that is not written out roughly as a series of lines in reading order, any arrangement of symbols that cannot be interpreted as an unambiguous move sequence. Exceptions to the examples above: small typographic corrections (e.g. blacking out moves and writing moves above that are clearly meant to replace them, moves written in subscript or superscript to fit between other moves).
 - E2c2++) [REMINDER] In the past, bracket notations (e.g. [r] or [u2]) were permitted for Fewest Moves. Only rotations based on x, y, or z are permitted now (see [Regulation 12a4a](regulations:regulation:12a4a)).
 - E2c3+) [CLARIFICATION] If a move is not clearly blacked out/scribbled out and it is not clear whether the move is part of the solution, the judge should consider it an ambiguous move sequence (see [Regulation E2c2](regulations:regulation:E2c2) and [Guideline E2c2+](guidelines:guideline:E2c2+)).
-- E2c4+) [CLARIFICATION] Examples of symbols or combinations of symbols that are not permitted in solutions for 3x3x3 Fewest Moves: M, e, r, Y (uppercase), T, U1, Ui, U3, U-, R++, R2', R'2, L'w, 1R, 2U, 2f, 2-3r, 1Rw, 3Rw, 2-3Rw, rw, Rr, *, →, ⮐, /, ., ?, [r], [r u], [F], <f>, [f]', [f]2, [x], (x), (L), 2(Rw), (U)2, (U)', (R U)', (R U R'), [R, U], [R: U].
+- E2c4+) [EXAMPLE] Examples of interpreting symbols or combinations of symbols that are not defined in [Regulation 12a](regulations:regulation:12a): [x] should be interpreted as x. (R * U', * = F2) should be interpreted as R U' F2. (R U)' should be interpreted as R U'. R++ should be interpreted as R. R3' is not permitted.
+- E2c4++) [ADDITION] Moves with both an apostrophe and a 2 should be interpreted as if there were no apostrophe (e.g. R2' should be interpreted as R2).
+- E2c6+) [EXAMPLE] Y should be interpreted as y. UW, uw, and uW should be interpreted as Uw. r should be interpreted as R, not Rw.
 - E2e+) [CLARIFICATION] Competitors must not derive solutions from any part of the scramble sequence, and solutions should not share significant parts with the inverse scramble sequence.
 - E2e++) [EXAMPLE] Example of solutions that should result in a disqualification of the attempt (DNF): solutions beginning with the same 4 or more moves as the inverse scramble sequence.
 - E3b+) [CLARIFICATION] Puzzles do not need to be solved at the start of the attempt.

         - E2a1) Before the attempt has begun, the competitor must not write on any paper intended for the attempt. Exception: the competitor may write information to identify the attempt (see [Regulation E2c1](regulations:regulation:E2c1)). If they write this information on the paper that contains the scramble sequence, they must write only on the side without the scramble sequence before the attempt. Penalty for writing anything other than information to identify the attempt: disqualification of the attempt (DNF).
     - E2b) All competitors have a total time limit of 60 minutes to find and write a solution.
         - E2b1) The judge should call "5 MINUTES REMAINING" at 55 minutes, and must call "STOP" at 60 minutes.
-        - E2b2) If a competitor joins an attempt that is already in progress (see [Regulation E6](regulations:regulation:E6)), their time limit is the time remaining (i.e. they must finish when other competitors reach their 60 minute time limit).
-    - E2c) At 60 minutes, each competitor must submit to the judge a single piece of paper with a written solution and information to identify the attempt.
-        - E2c1) Information to identify the attempt is: the competitor's name, WCA ID, or competition registrant ID (at least one, optionally multiple), and optionally the competition name, round, or attempt number. Penalty for a submitted solution without name, WCA ID, or competition registrant ID: disqualification of the attempt (DNF).
-        - E2c2) The solution must be a single unambiguous move sequence with each individual move written out in sequential order. Penalty for an ambiguous solution: disqualification of the attempt (DNF).
-        - E2c3) The competitor should clearly black out/scribble out all moves on the paper that are not part of their intended solution.
-        - E2c4) The competitor's solution must only use moves that are exactly defined as notation for the 3x3x3 Cube in [Regulation 12a](regulations:regulation:12a), and must not use any symbols or combinations of symbols that are not specifically defined there. Penalty: disqualification of the attempt (DNF).
-        - E2c5) The competitor's solution is considered correct if starting with a solved puzzle and applying the scramble sequence followed by the solution results in a solved puzzle. Penalty for an incorrect solution: disqualification of the attempt (DNF).

Penalty for a submitted solution without information to identify the attempt: disqualification of the attempt (DNF). Information to identify the attempt may be added by the competitor after the attempt has been submitted but before the end of the competition, at the discretion of the WCA Delegate and under the direct supervision of a judge. The competitor must not write anything after the time limit without the judge's supervision and must not make any changes to the solution. Penalty: disqualification of the attempt (DNF).

+        - E2c3) The competitor should make it clear which moves are intended to be part of their solution, by clearly blacking out/scribbling out any moves to exclude, or by drawing a single outline around their solution.
+        - E2c4) Only numbers, letters, and apostrophes are considered as part of a competitor’s solution. Other symbols are disregarded. The remaining solution must only use moves that are exactly defined as notation for the 3x3x3 Cube in [Regulation 12a](regulations:regulation:12a). Penalty: disqualification of the attempt (DNF).
+        - E2c6) If a competitor used incorrect capitalization for a move defined in [Regulation 12a](regulations:regulation:12a), it should be interpreted as if it has the correct capitalization and accepted as valid notation.
+        - E2c7) Any writing or other markings on the solution sheet which are clearly not a part of the competitor's intended solution may be disregarded, at the discretion of the judge.
+        - E2c8) Competitors must not intentionally make their solution harder to judge by using moves or symbols not defined as notation for the 3x3x3 Cube, incorrect capitalization, or by any other means. Penalty: disqualification of the attempt (DNF) at the discretion of the WCA Delegate.
     - E2d) The competitor's result is the number of moves in their solution, calculated using Outer Block Turn Metric (see [Regulation 12a5](regulations:regulation:12a5)).
