Document how notifications work, especially in regards to issues and translations

[jhoffner]

A new update was recently made that will notify kata co-authors if an issue is logged and the author has not been active within the last 2 days.

These types of rules should be documented.

Hi, not only that what was already mentioned... I haven't received any email notification so far from the Codewars project although there surely could be some (like when someone for example upvoted some of my comments (although I can't see who - is this correct?)).

So I wonder under which circumstances will I get some notification? My notifications' email etc. seems to be setup correctly...

BTW Generally, I don't know if it's just my feeling, but the project seems a bit under-documented in more areas - like regarding the shortcuts (of the UI, of the Code Editor)? But otherwise, it's a great project! :)
