This FAQ was written as I was just getting Picofarad started, so they couldn't very well be frequently asked questions...
Gaming: A general gaming convention runs the gamut from tabletop role-playing to collectible card games to board games to LARPs.
LARPs: Live-Action Role-Playing games.
Media: Focused on movies and TV shows rather than books.
Relaxacon: A small convention for those who would rather just sit around and chat. The traditional big events of a general sf convention will be scaled down or omitted.
Symposium: An academic gathering for the presenting of papers and scholarly discussion; none of the events of a typical convention.
Art: For drawings, either GIFs or JPEGs are fine. Picofarad's printed page size is about 4.5" wide by 7" high. It's printed in black only, but with a colored sheet for the outside pages; if you send cover art, feel free to suggest a background color.
