There have been a number of times at night when I find myself with enough time that I could play a game that I would love to be able to log in to Roll 20, pick up a little one shot game, or set up something myself and have people join on the fly. It would be nice to be able to flag a game as open and waiting for players so that I could look at a list of games people are sitting in waiting for new players, or a game that a new player could drop in to easily. Once the GM feels there are enough players the flag could be turned off in the game and it would be de-listed. I understand from another thread on here that open chat rooms can get messy, and this seems like an elegant solution for everyone.
