There are two ways a student may join a club.
For incoming students, you can fill out a recruitment form on the club's website. When you click submit, the information is sent to the club, who will follow up with you via email or phone to answer your questions and discuss the club with you.
For new and returning students, UIW holds an "Information meeting" each fall and spring. This is a day near the beginning of each semester in which all clubs are present to help any questions new students may have about the team and schedules. These days are an opportunity to join a club, speak with members of the various clubs, and learn more about each club.
