is anyone familiar with Trillian?

I'd like to try to give it a shot, but would like to know if Quick Time 6 is really a necessary accompaniment. During the installation process (of Trillian) yesterday, I was told that Quick Time is needed for "conferencing" (or something similar). Thinking that the term might include chats with multiple IM buddies, I clicked on "yes" to download/install Quick Time, but the processes (both Trillian installation and Quick Time download) froze after a while.
I did a system restore to the previous day, to make sure there were no traces of my last attempted installation, and I downloaded Quick Time directly from the Apple website this morning. I plan to try installing Trillian again, but before installing Quick Time for it, I thought I'd ask if anyone knows whether QT is really needed in order for Trillian to function properly. I don't plan on doing any official "conferencing ", as in a work sense...
Thanks!

 

A couple of hours later, I've found my own answer: QuickTime is needed for webcam function, which I'm hoping to start using, so I guess I'll install QT after all.
For anyone unfamiliar with Trillian, here's what it says about it at download.com:

Trillian is a fully featured, stand-alone, skinnable chat client that supports AIM, ICQ, MSN, Yahoo Messenger, and IRC.

Without stealing your home page and with no other included software, pop-ups, or spyware, Trillian provides unique functionality such as contact message history, a powerful skinning language, tabbed messaging, global status changes (set all networks away at once), Instant Lookup (automatic Wikipedia integration), contact alerts, an advanced automation system to trigger events based on anything happening in the client, docking, hundreds of emoticons, emotisounds, shell extensions for file transfers, and systray notifications.​

Found out about it in another post here about favorite freeware, and thought it sounded like a good idea!
