The argument below is true of every community. What it looks like in practice is not — a club has fixtures and subs, a clan has a roster and applicants, a residents' association has neighbours who will never open Facebook. Each of these is a page of its own.
Sports clubs
Fixtures, notices, subs and a committee room — for GAA, soccer, and any club run by volunteers in their own time.

Residents' associations
A noticeboard the whole road can reach — including the neighbours who will not go near Facebook.

Discord & Slack communities

Facebook groups

Gaming clans
Rosters, builds and recruitment that do not scroll up the channel — and something an applicant can read before they join.
