I haven't posted here in ages, but this one is close to home for me. I am not a Second Life expert, but I have checked it out because it's all the rage in my profession (librarian, go figure). I'm going to make a crazy suggestion. Why not try an Apostafest in Second Life? Anyone could attend, it wouldn't matter where you lived. I'd be there in a heartbeat. I have been looking for a good reason to use it.
I don't really consider Second Life to be a game. It's more like the next step for myspace.
