There was a great post on the Unity forum the other day which I thought would be worthy of converting into a Wiki (not presently done). The user had categorised lots of free/cheap resources for Unity.
From what I can tell, converting/flagging a post as a Wiki only seems to remove the limitation of the OP updating it, thus anyone can update it in Wiki fashion. The only downside that I have seen so far is that the Wiki posts are a little scattered to the wind, e.g. if I wanted to specifically find those resources again I would have to bookmark or search, if I were a new member I wouldn’t have already booked marked it, any may not thinking to search, or use the wrong terms.
With your mention of creating some custom SQL regarding the badges, I wondered whether it may be possible to do something similar for posts that are converted to/flagged as Wiki - and then have them all appear under a non-postable sub-forum linked with the other categories for each course?
For example: Under Unity where you currently have Programming, Public, Collaborate etc you’d also see a link to Wiki. The sub-forum would load and be populated with any posts flagged as Wiki from that Course.
I’m guessing comments on the original post remaining after flagging as Wiki, but it could be beneficial to not pull those through with the SQL, just the main post - that way there is a very clear, concise return of information. In the same way I don’t think being able to post a new post to the Wiki’s sub-forum would be appropriate, it should just collate from all other sources for the course (like an RSS feed I guess).
Suggestion only, appreciate it’s a bit of work - am actually surprised that something doesn’t already existing to support it by default?
