Meet management made simple.
Divisions are a means to group events. Every event MUST be in a division, so your meet must have at least one. This is generally something like Varsity, Open, Community, or JV. If you have separate events by age group then it might be Bantam, Midget, Masters, etc. In some meets there might be a Open, Invitational, or Elite races that might be put into separate divisions.
When doing a track meet, division will determine the team scores. In other words, it will by default set one set of team scores per division.
This is pretty straight-forward. You can edit divisions from a number of places... generally either from the Divisions button on the Setup Tab or from the link when adding or editing an event.
The window has Add, Remove, and Edit links whose names are self-explanatory.
