Hey, anyone running AIM on Windows ought to checkout
Deadaim. It's a AIM hack but it seems to be just as stable in the last few days I've used it. You can have all your conversations in one tabbed window as to prevent your taskbar in WinXP for doing a waltz every time somebody sends you a message. It also has online/offline alerts like MSN Messenger which is useful. Oh and a log manager too!
Anyhow, for free software it's awfully useful. Oh, most importantly those gaudy AOL ads are taken out praise-the-lord.
