How to deal with lack of participation

[Fields]

Our team only met a couple of times last fall being our first year and not knowing what to expect.

How often do some of you meet in the fall?
Obviously, with enough effort you could meet and do stuff every day, but I don't want to burn out the students OR the mentors.

Right now, I'm thinking about once every two-three weeks mostly for figuring stuff out for next year. Then maybe once a week in the fall for training/team building/media/practice/hangouts.
