I just start using a very cool open source install messager called Gaim. This instant messager can connect to both ICQ and MSN, both accounts are unified in a single window. I can send messages to my friends in both network exactly the same way. I no longer have to open two messager and take up large chuck of my screen. I would like it to have a few more extra features to be more user friendly. The contact list is not compact enough, each row of contact is a little bit too wide. I can’t arrange the contact list freely and it doesn’t show offline users. Other than these kind of minor visual problems, Gaim is a very convinient and very usable piece of software

You can download Gaim at here.
