Looks like only users with Discourse trust level 3 (“regulars”) can create wiki posts, but anyone with at least trust level 1 can edit wiki posts: Understanding Discourse Trust Levels
Are there additional differences between a wiki post and a normal one, other than the shared editing of the OP?
E.g., are they discoverable in some other way or something like that? I couldn’t find anything in the sidebar that seemed to show only wiki entries at least.
Edit: And how do you find you trust level? I could see I had a badge for “regular”, but I can’t see the wrench that @mkitti shows.
Edit2: Trust level found in profile summary and press expand in the top section. And I do seem to have the wrench, but just on some subset of my own posts from what I have found so far.
