Trillian is a sophisticated and powerful tool for communicating with your contacts via instant messaging.

The program can also operate all MSN, Yahoo Messenger, AOL Instant Messenger (AIM), ICQ, and IRC accounts at the same time.

Trillian is fully compatible with all these servers, has its own environment (very comfortable and easy to use), and can be configured via “skins”.

The program also supports input and output logging, allows the use of emoji, and has a unique icon system to distinguish each connected contact.

If you have multiple accounts on different servers, this is the application you were looking for.
