Also try contacting the former faculty advisor. Every school club to my knowledge is required to have a faculty advisor. You should contact previous members and faculty advisors to see if they are interested in playing again and you can get advice on how to run the club. If no previous club existed, you should go to either the Campus Recreation office or Student Activities office and request to start a new club. Usually you will have to fill out paperwork and obtain a faculty advisor to oversee club activities.
Every school has different guidelines as to how a club is started so take that into account.
At first the club will probably consist of just you and your friends. Your goal is to expand to greater numbers. Inviting high-level players from the local area to do the exhibition will probably attract a lot of attention. The important element is to promote your club to anyone and everyone. All that is needed to join are four or more commited players from your school.
