Exactly my thoughts. If SocialHub admins cannot ensure smooth entry into the forum for members who don’t already have an account, I’m not sure it’s the right place for the Fediversity category.
@aschrijver would the admins of the Social Coding forum be willing to host the Fediversity and have it federating over AP? That way people could interact with discussions there from the fediverse, without needing an account on that forum.
EDIT: With the right tweaking, the category here could eventually be federated, and crosslinked with a new one.
