-- add non-LJ Jabber addresses to your LJ Talk buddy list,
-- rename roster items,
-- move roster items between groups,
-- accept presence-request invites from JIDs (both LJ and non-LJ).
-- cancel/nak presence-request invites from JIDs (both LJ and non-LJ).
-- remove LJ people from your roster (but without de-friending them)
-- etc, etc.
Basically s2s (server-to-server) communication was severely hindered up until now without the ability to put non-LJ JIDs on your roster.
But it should be all good now.
Enjoy the Jabber federation!
I'm going on vacation now for 3 weeks. If you don't hear from me until August 1st don't think this project is dead or anything. Please post bug reports here and the reliable burr86 will read them all and report them to us when we get back. (a couple of us are going on vacation around the same times...)
