But, there are some problems...
-it take 2-4 minutes until it goes online
-the connection process slow down miranda
-I get strange contacts in the root group. E.g. one contact with a groupname and it duplicate another group.
-Move in groups not work, unfortunately I find no way to do this on the FB site, with the new design.
(okay found this, Account->Edit friends)
-Seems to me that is the same thing than this google jabber server, not any service
