A lot of what Kathy already said is what my team does. We have a meeting with all possible new recruits and explain how things work, what needs to be done, basically a question and answering meeting so the new students arent going in cold feet. We attend off season events such as Bash @ the Beach. We do fudraisers; car washes, pasta dinners, raffle tickets, some students help out our 4 FLL teams. (3 in Suffield, 1 in Windsor Locks) Clean shop; get it ready for that big day in January!
There's definitely lots of things that could go on. Theres some ideas.
