How do I add a group or change their order?

The owner does it in the Groups screen.

1. Open Schedule, then See groups, at the top of the screen (or Settings > School > Groups).
2. To add: tap Add, write the Name (at most 80 characters, unique regardless of capitals), choose one of the 8 Colour options, an optional Description (optional) of at most 200 characters, then Save.
3. To change the order: drag a group's ≡ handle.

This order is the one of the Group drop-down for students. If the name exists already: "A group already has this name." Groups are optional. An instructor cannot manage groups.
