OB's Theater usually features something interesting, whether you're a reader or a writer. I'm happy to say that even when things go quieter, we still have a pretty good selection of new RPGs for people to join. Here are just a couple of the ones that have cropped up within recent weeks.
Adventure of Space Bounty Hunters (by Dragons Wolfie)
Hood (by DeLarge)
There are others recently that have either just started or are on the verge of doing so. Even if an RPG has just started, I recommend sending a PM to its creator if you're interested in joining.
