Well, just in case you haven't heard the hype yet, GimICQ is a test release of the ICQ portion of Gimmick. Gimmick is a "mega chat client," capable of handling AIM, ICQ, Jabber, IRC, and whatever else we feel like adding... all in the same program.
Our Review: Unfortunately, this software isn't supported anymore. It also isn't being developed anymore, which is a shame since it had great potential. The interface is good-looking and it was definitely on its way to being a decent communications application. Luckily, there are other programs out there that fulfill the same function as GimICQ (check out ICBM). GimICQ is probably the best ICQ client for BeOS at this stage.
