Hi, guys does anyone know how to clear all the chat history for all the people i talked to on jivetalk. I noticed it keeps track of all the chat history for all the people. how can i clear that . thank you

In JiveTalk's preferences you can turn off chat logging. I'm not sure if you can clear all the chat history all at once, but I know if you open the menu while highlighting any buddy (online or offiline) there's an option to clear the chat history for that buddy.
