If you don't know what CSL is, check out this post: http://www.cstarleague.com/node/82
You can be a graduate or undergraduate student at the main campus or one of the branch campuses (as long as the rules are the same as last year). I believe PSEO students are not eligible, but if you are full time and want to join we can double check though.
Registration opens August 25th and ends September 25th, but you can join the team before that unofficially. We communicate through Facebook and it's worked really well for us, but if you don't have an account we can work something out. If you're interested in joining, PM me with your name, link to your Facebook if I can't search for you, and OSU email (to confirm you're a student, and to register you for the team).
