@crossgolf_rebel - kostenlose Kwalitätsposts @Dr. Amy, Psy.D. Mastodon users (among others) can at least participate in these #Friendica-groups. But only Friendica users can create and moderate the group.

Here is a directory of Friendica groups. Some are completely public, e.g. this support forum, others are restricted, i.e. the moderators allow access (or not) and can also remove accounts from the group.
