I remember trying a couple of them a while back, but I don't remember the names. Bayden had one, and I think Siviard did too. There weren't many people in them, and I found that simply being gay isn't really enough to tie people together toward common cause in the game. Attitudes and goals vary, and players naturally migrate toward where theirs coincides with others'.
My advice: find a group based on what you want to do in the game, not on a single aspect of someone's real life characteristics. There are a lot of gay players in the game, and you're more likely to find them and make friends just by being yourself and joining a group with common in-game interests based on your level and play-style.
