Yeah, pretty much, people just talk about whatever. There is a general hangout and chat thread where usually most of the activity happens. As I understand, there is some slight RPing from time to time, too. Everyone seems friendly so far :3
I am currently in 2 guilds, both social ones. Most of the members are GCDers, but topics of discussion are not really centred on the GCD. One is more active that the other one though. If you want, I can recommend you for joining. This is the more active one. If you want, I can show you the other one, too.
Truth be told, I am on Gaia because of the awesome avatars. I just love dressing up my virtual dollie XD I have not been talking to pretty much anyone here for almost 4 years before getting an invitation to my guild. And I asked because I thought you needed help with something. I could start honing my rusty fishing skills again if you did. Do you use any messenger these days? The only way I know how to contact you is FB, otherwise.
