We've got a couple archived listings, but that's usually a sign that the group may not be active anymore.

There's also this Linkshell, http://na.finalfantasyxiv.com/lodestone/...694428067/
If you're looking for some small, tight-knit RP, you may be able to work it out on your server or another one of the smaller ones (Jenova and Siren come to mind for me.) For a bigger selection of RP possibilities, Balmung's probably your best best though. I wouldn't call a community as much as a bunch of different options. (It's got a wide variety and people can often find or make what they want)
