+subscribe: nickname of a user account to automatically subscribe new
+           users to. Typically this would be system account for e.g.
+           service updates or announcements. Users are able to unsub
+           if they want. Default is null; no auto subscribe.
+welcome: nickname of a user account that sends welcome messages to new
+         users. Can be the same as 'subscribe' account, although on
+         busy servers it may be a good idea to keep that one just for
+         'urgent' messages. Default is null; no message.
