Events can be categorized into different groups, both to organize in a list format, and to control how schools sign up for events. Each competition must have at least one group (named “Default” by default) which the events belong to. Other groups can be set, and the display colors of the groups modified by the competition organizers. Each competition can have up to 255 event groups defined (one-byte unsigned integer in the database).

Organizers use the “events” page to add and remove event groups. To add a new event group, use the blank line below the existing groups. Edit the existing data in the lines above. To delete a group, move all existing events from that group to another, then delete the “order” number for that group and submit the form.
