What can each person on my staff do?

There are three jobs:

• Owner. Everything, including paying for Leagology, adding and removing staff, and changing the business's name.
• Co-host. Runs competitions: sign-ups, checking players in, pairing them up, scores, results and photos. Can also change your venue's page. Can't touch the bill or your staff.
• Referee. Keeps score on their phone, on any table you give them or any table nobody's been given. No sign-ups, money, venue page or staff.
