Last change on this file since d06eabf was d06eabf, checked in by Wilmer van der Gaast <wilmer@…>, at 2007-06-04T13:22:05Z
Added imcb_buddy_nick_hint so the Jabber conference module can suggest sane nicknames for chatroom participants. There'll probably be a lot of underscores now, but this is by far the cleanest way to implement this, I think. At least now whispers will work properly. Also using this function call to set names for ICQ contacts in a slightly saner way.
