I'm on the event team for an annual gaming convention based in Providence, Rhode Island called TempleCon (http://www.templecon.org/). The convention has a great deal of 40k action that goes on during the weekend, but this year some have asked if we'd be showcasing any Dark Heresy as well on our role playing schedule.
So I figured I'd check here to see if any interested DH GM's near the area would be interested in coming out and running some games for us during the weekend on February 6-8th, 2009. Either full weekend campaigns or one-shots would probably draw a lot of interest. I also think we could talk with FFG about getting some swag to give away as well.
As for the convention itself, it's a great time, in a pretty amazing venue, and staffed by some fun people. Check out the website above for more info, hit the event proposal page, or shoot me an email with your ideas.
