This year RPG Geek has decided to organize an online virtual convention. It will run October 18-20th across many time zones. RPG Geek's been a pretty great community to participate in, with solid and interesting participants. Beyond that it offers a solid and comprehensive database of RPGs, along with the ability to record and track your collection. I've used that resource to track down new games in genres I enjoy.
I'm going to be running two events for the convention; I'll post the specifics when everything is finalized. They're still looking for more GMs and events. If you're interesting in running an online game for a pretty solid group of gamers, consider pitching in. They'd like to get a few more events before the event reg deadline of July 15th.
