This post may be removed since it advertises another Star Trek group, but if you are serious about simming check out
Star Trek Simulation Forum. There are a group of Advanced Sims that cover just about every Trek era, including Klingon and Romulan, and Academies every night except Friday.
We are also officially recognized by (although not part of) Paramount Digital Entertainment, owners of www.startrek.com, and are the only sim group who can officially claim that.
Several startrekfans.net members are members of us as well.
