Minimum size: You probably don't want to lose any members, but a typical "skeleton crew" for competition is 4 (3 students, 1 mentor).

Ideal size: If everyone is doing something and doesn't have too many things, you're at ideal size. If you have more people, make more things to do to make sure you're at ideal size.

Concentration: Depends on the team. You can do it that way, or have everyone doing everything. You make that call.

Suggestion: Make sure that you also recruit mentors. Parents might be a good place to start; see if they know people who'd be willing to help out.

Suggestion 2: Have a team handbook.

Suggestion 3: Talk to teams 341 and 365 about their rookie resources.
