If you wish to join your house Quidditch team, the only prerequisite is that you are of second year or above. Watch for your respective captain to announce tryouts, or go ahead and @mail them to see if there are any openings for you! Even if the entire first string is full, most captains will accept alternates.

Captains are reminded to keep their rosters updated by notifying Collin of any changes via @mail.
