This is true, and I'm working on branching out with the help of a good friend, as well as trying to interact with my SG more. But I thought it would be a good idea to try and forge more relations on my own, because I don't want to be overly reliant on a very small handful of people with their own lives, I've just been having trouble with that. I love my SG and I probably don't have the time for another one on top of that, but we are still small and most folks aren't around every day. I've been able to RP with 2 or 3 outside event times so far.
By the time I found out about it, it was pre-existing. I don't know who made it but it was a whole forum section of its own on a "Roleplayers coalition" community forum.
