Bloated pile of donkey feces!
Not only is this bloatware, and a memory leaky resource hog, it also costs money for a version that has less features than the FREE Miranda client. Plain trillian has almost as many features as AIM+Aimuation (or any other base protocol + freeware ad-removing enhancements). If you really want to use mulitple identities or multiple protocols or both at the same time, use skins, and a host of plugins then you want to stay away from trillian like you would a notorious brothel.
You need to get youself a FREE copy of Miranda:
http://miranda-im.org
It has a FRIENDLY support community -- unlike the liberal cretins that troll the cerulean forums.
