I have new things found which i want to suggest.
1. There is no way to disable the „xyz is now online”, „xyz is now offline”
Messages that appear if a conversation window is left open.
2. Wenn pidgin sends a linebreak it sends <br> which is not translated by
jitsi but displayed. I am not sure if this count as bug for pidgin or for
3. The OTR Plugin in pidgin has a message „You are sending encrypted
messages to xyz who isnt expecting this” if the state of OTR was one and
the contact is now at differnt machine (without OTR). So you have a simple
way to tell if you should refresh or disable OTR.
All three points found with icq.
