There are 2 programs that sound a lot alike Windows messenger and MSN Messenger. The first one is the one that allows you to get slammed with all kinds of adds.
The second one is the chat program thru MSN
Trillion is a program that allows you to combine all of them into one interface.
The only problem I’ve found with trillian is in the file tranfers part of the program.
For that, I still find ICQ the best program to use.
