Setting up: how often should they meet?

Charisma meets once a week, 3-5. Each year when we begin we ask the editor to choose meeting times. Monday evening is what's usually chosen. Two hours goes fast and allows us to do a lot of things. I think that meeting twice a week might be better. However, my schedule and the students' schedules don't usually allow a second weekly meeting. Mike and I don't do this group as a club that meets during Club Period (once a week) - in the past, students have been dumped into the club, and very little gets done when that happens. Also, we've talked about turning Charisma into a class, but then people wouldn't be able to grow up in it - some come in as Freshmen and do it all four years. In the past two years we added an online blog, but that has not been used to its potential.
