New engine, fresh start.  Previous accounts could not be migrated — please re-register here or via your XMPP client. Still in early testing.
Apology to the federation.  Over the past days our MUC service left ghost occupants in federated rooms under certain conditions, which caused repeated presence join/leave storms. It was not intentional — we did not want to flood channels. The fault is on us; our dev is simply a hollow nut on this one. Root causes (XEP-0045 §7.14 directed-presence tracking, §18.1.2 kickable-error list, §9.1 actor/reason in kick/ban) are fixed as of Zerta cd944f8. This will not happen again.
