Event Store docs are hosted on GitHub. The repository is public, and it’s open to pull requests. We’ve got a bunch of goodies, beer tokens and more ready to send out to people who contribute.
User projections are not enabled by default, however the projections engine is used internally for account management. If you want to run user projections, it is necessary to start using the --run-projections=all command line parameter (or equivalent as per the [command line arguments]({{ site.url }}/introduction/command-line-arguments) page).
Projections are still experimental and as such we have not yet documented them here. However, there are two series of blog posts about how they can be used, which are listed below under the Related Blog Posts section below.
The following blog posts talk about the Event Store and may be useful for features that aren’t yet documented here. If you know of any others, please let us know!
