If you had trouble entering your school details when registering, or are in a team from multiple schools, or would, for whatever reason, like to edit the affiliation for your team, then you (or rather the Team Captain) can. You can choose to do nothing, but if you want to make a change then get the Team Captain to head over to their account page where they should see a message from me telling them what to do. Hope it is obvious once you get there.
