I'm not at college level yet, but I know people who are. It's a real time-filler, you should really focus on that, at least for the first few years. If you'd like to keep in touch with other teams, I highly recommend Skype. Free PC-to-PC calling, now includes video (so you can see their progress
), and
very cheap calling rates for PC-to-phone.

I'm starting a new team, too, and it is VERY time consuming, not to mention a bit stressful. Your "business" plan is a good idea, if the students you are trying to appeal to are interested. Every region, city, and team uses a different approach or angle when trying to reel in more students and sponsors, if it works then kudos to you!
