Improv Resource Center - Forums

I'm building an improvisation resource web site geared towards servicing improv groups in Chicago. Basically, it will provide groups with an interface to create free, customizable web sites, (similar to Geocities...) and online calendars to advertise their shows. I'm also trying to develop a few useful tools, one of which is a resume wizard. It will take the improviser through a series of questions, and, through those, develop a nice, clean, printable resume.

I'm in need of a resume expert... What information belongs on a theater resume? For simplicity's sake, I'd like to have just one template. What items are essential, and what order is preferred?

Thanks so much for your collective input... I appreciate your help!
