||Only publicly listed rooms
||Only rooms which can be joined without password/invitation
||Publicly listed MUCs where owners have requested de-listing from this directory
||Total number of users in all MUCs. Since we do not (and can not) track the real identities of users, this most certainly includes duplicates.
||Number of domains known; this includes non-MUC service domains and usually a single XMPP service has multiple domains (e.g. a base domain and a MUC service domain).
||Number of domains which haven’t been reachable for more than 24 hours. Domains which are not reachable for more than seven days are removed from the database, unless they are being advertised by other domains.
