Instructables is a great community for sharing How-Tos , and "How to Start a FIRST Team" has garnered some interest there:

If there are other team members, coaches or mentors on Instructables, it's a good place to share FIRST related how-tos across all categories, and potentially reach more students and mentors in a fairly mainstream platform.
Also started a collection of FIRST related Instructables here:

Enjoy!
