You can modify existing divisions for your competition in the "Programming" section of your competition dashboard.
While managing your competition:
Select “Programming” and then click on “Divisions”.
You will see your existing competition divisions such as Women Scaled listed.
To modify a new division, click the pencil editing icon towards the right side of the division listing (circled in red in the example shown above).
This opens a form (pictured below) which you can use to modify Division Name, description of the division, Team Size, and maximum number of registrations allowed. You can also specify whether the division is for Athlete, Volunteer, or Spectator registrations under Type of Division.
Make your modifications, then click "Save".
