From the Dashboard, Select "Club Management" followed by "Roster Builder"
Here you will select the "Event" that your teams are registered to and hit submit.
If you do not see any events to choose from, click the "Add Roster Season" button tor create your own internal rostering event. Input the event information and click "Save".
Once here, you will click and drag the hairpin icon next to the player's name, to the team you would like to roster them on.
Note: All the players on the team currently have green checkmarks that signify approved by the event.
You will now see that player on the team with a Yellow Triangle next to the name since the player was just added and has not been approved yet.
All New players will appear with Yellow Triangles until the roster is approved by the event.
