Starting an After-School Computer Club?

Kai_MH asks: "When I moved up to my high school this year (I'm a Sophomore), I was surprised to find that there was no 'computer' or 'technology' club at the school. Sure, there's A/V, but what fun is carrying TV sets around? So, I'd like to approach my school's administration about starting an after-school computer club. I'd like to educate my peers on the alternatives to Windows (Linux and Open Source), how hardware works and fits together, job offerings in computer-related fields, and anything else that may be of interest. Perhaps we can do fund-raisers to build and upgrade a computer for the club, which could be donated to the school or community? Does anyone have suggestions on this? Has anyone tried this before? I've had a lot of support from my peers, but I'm still not quite sure how to go about it."
