Sure...I've been using Trillian for 4-5 months now...it is a little 'different' to get used to, but 92.416% of its features are superior to ICQ...and....you can have 3-4 identities at once with Trillian, in case you want to be Betty Broccoli in your vegetable fetish group.You can even have Trillian & ICQ open at the same time, with different privacy settings in each...not for everyone, but it is a good product.
(The gang in the alt.comp.freeware newsgroup seems to be about 10-1 in favor of it.)
