Did a little research and there IS a feature that would let everyone know who is in the "holdem" game.

However, it's actually quite a bit of work and I think it would "bog down" the forums for everyone.

So I am not going to install that at this time.

I would suggest typing in the chatbox if you're available to play. That way, if there are at least two people around who want to play, you shouldn't have a problem getting the game going.
