Once you have navigated to Reg Mgmt /Rosters, within the season you are utilizing, you can filter specific data to find the players you want to work with.
In this example, we will look for players not currently on a "Team".
Click the "Filter" button located next to the search box.
Add Filter.
Select "Team Name" from the drop-down. (This drop-down will contain every item that was collected during the registration process)
You would be able to either select "is blank" or "Equal to" a blank space to filter for players that are not on a team
Click Apply, and the system will only show Players without a Team assigned.
