The largest multi-genre convention is taking place this weekend in Atlanta: Dragon*Con. Fans of every stripe, from sci-fi to anime to videogames to comic books, descend on ATL to revel in all things geeky. We want to know if you're going!

Take a look at our Field Guide to the Geeks of Dragon*Con. If you're out and about and make an excellent sighting of one of these superfans in a killer costume, take some picture and video, or get up close and personal for an interview. Or, if you're a proud geek who wants to represent your fandom, snap a picture of your group in-costume at the convention!

Share your photos and videos of the costumes, panels and parades. Tell us what you're interested in seeing, and what cool things you uncover. The deadline for this assignment is 8pm Sunday, September 4. The best submissions could be featured on CNN.com!
