A few days ago, I have discovered something very useful for us instant message users. It's called Trillian, and it is (excuse the expression) fucking sweet! Basically, it's a skinnable, completely customizable, ad-free, and fully-functional ICQ, IRC, AOL Instant Messenger, MSN/Windows Messenger, and Yahoo! Messenger client. Moreover, MSN/Microsoft Passport integration allows for very quick, handy-dandy Hotmail checking. Trillian features an easy-to-use, all-in-one ICQ-like interface. The creators welcome users' comments. It gets better with each release. Needless to say, you can login to all five services and administer them simultaneously, group wise (i.e. you can set "global invisible mode", or "global away mode").
