But I'd like to complicate your life.
This isn't "A" convention. This is a family of conventions, held at different times, in several major cities. If you hold a single convention it will have a very limited impact. The problem is at least North American in area - probably worldwide. What should be put together is a skeleton, on which local artists/writers/attendees can add their own variations.
And if there is one held in Toronto, I'll probably volunteer. I've worked Ad Astra, Toronto Trek, FilKONtario, and Torcon 3 in the past.
