I discussed this with Kieran, and we no longer support co-author functionality (this code has also been commented out in the codebase).

Saurabh, please update our EasyCLA documentation to remove references to co-author and explicitly state that it is not supported.

Thank you!

@mlehotskylf,
I have removed this topic that you could see related to a co-author compliance.

Thank you @ssinghlinux1989 , we just need to add more details about not supporting co-authors. I will come up with the text and let you know. Moving this to In Progress.
