Each week after the school year begins, FLO sends out a weekly newsletter that will keep you up-to-date with all things FLO as well as provide some humor to relieve you from the school week for a few minutes. Since FLO has no fees and no application, this is basically the one step you need to take to become an official member. (Although, coming to the meetings would be nice too.) :p
Sign up for the FLO-down here.
Shortly after you sign up you should receive an email from Director, Amanda Goodson.
