I am struggling with this. Closing the wiki doesn’t work for me for the same reasons mentioned. It’s makes total sense to have the first post as the wiki, and the subsequent posts for discussion. Any edits to the first post should bump the topic to the top of the list. Users on the forum are checking latest and complaining why the edits aren’t being bumped.
The solutions mentioned here are exactly what I wanted to happen. Can this not be added?
