The Gamesmaster (GM) is in charge of running the weekly socials, picking which games to run and ensuring that everyone is having fun at them. The Gamesmaster is the role that most members of the society will engage with on a weekly basis, so they should aim to be friendly and sociable, as well as good at communicating to groups. The GM should also aim to make sure that socials are as inviting and inclusive as possible, making sure that everyone feels comfortable and has the ability to de-stress. 

As a note, Gamesmasters are expected to attend as many socials as possible in order to ensure smooth operation of the society.
