Maybe something like a "general tech help" group. Where teams can divide up the country and do something a bit like "Geeks on Call" to help people with various computer/technology issues. Stuff like:
- "The internet is broken!"
- Set up my new hifi system
- "My radiator needs to be flushed, and my tires rotated."
Okay, maybe not that last one, but you get the idea. We pool money for advertising and such...
