Windows Live Messenger with easy to use, customisable interface that allows you to chat with friends is a piece of cake. The program will record itself when it detects Internet connection or when you start the program themselves. There are several ways to organise your contacts and add new easy.
Doublecheck options within the app and see if there is a setting to keep you logged in always.
Also, it may be automatically logging you off when the handset locks (if you have a password enabled). Yahoo Messenger does that, by design. Don't know if that's the case with WLM or not. Posted via BlackBerryForums.com Mobile
