ajack you can delete the conversation through the menu of a conversation window.

You can also go to /home/user/.yappari/logs and delete files individually.

Yappari is alpha. When Yappari is ready it'll be in the repositories so there's no need for an external server to notify about your updates. I do need people read this thread all the time. You guys are supposed to be testers, not users, and this thread is our method for feedback. Yappari shouldn't be used by final users yet.
