Well, I had an idea earlier this year to start a new convention with these forums in mind. The idea seemed like it would take off, but as usual, when people try and glorify God, things get in the way. Heh. Anyways, I believe it's a part of my calling to try and get it started for real, but it will require a willing and vigilant team, funding, and a location, as well as a date, con length, and admittance fees.
If you wish to help, or know anyone who you think can, please let me know.
