There's a bug with moderated membership for communities. Users are able to request to join and the notification is sent to the admin, who approves the membership and gets a 'success' message. But those new members don't show up in the membership list on the profile or on /community/members.bml.
Admins are able to send invites to users, and users are able to accept the invitation, at which point in time they receive "you are now a member of $comm" message, and the invitgation shows up as accepted. But just like in the first case, users don't show up on the profile or /community/members.bml.
We also tested for functionality - people in this situation can't post entries.
(Incidentally, this affects dw_beta
; if you requested membership sometime after mid-March, I approved you, but you can't see that.)
ETA: moderated membership is working correctly, but if you approved people during the downtime, you have to re-approve them all.
