kargakis: Also, if one wants to help out, they can click Watch on mimblewimble/docs. Then every update on the wiki shows up in your activity. The deletion is obvious in the git history, the only problem is that you have to pull the wiki locally in order to see that.
Another thing that I forgot to mention during the meeting is that when a page is deleted in the wiki, its hyperlink (if included) in the sidebar shows up with red color, so it can still be obvious just by looking at the wiki via the UI that something is deleted.
