Quidditch Captains are decided based on seniority, but must be in at least fifth year. Quidditch players during this time period were typically male, due to the rough nature of the sport. To take a vacant spot, post in maintenance. Be aware that female beaters and all first years can join the team via IC tryout only. Hogwarts does not have second string quidditch teams.
