I’ve seen myself and many others posting events they have hosted in the General category, and while that seems pretty suitable, a “Community Events” sub-category to the General category would help for this who want to see what others are hosting without having to sift through other posts.
Heya!
I actually made this suggestion a while ago. Glad to see it getting more attention, though!
