Step One:
From the Dashboard, select "Club Management" and then "Roster Builder".
Step Two:
Here you will select your "Event" and hit submit.
Step Three:
You will click and drag the hairpin icon next to the player's name to the team you would like to roster them on. A popup will appear allowing you to set a position or jersey number for the player if you choose to do so. Click "Add Player".
Note: All the players on the team currently have green check marks that signify the player has been approved.
You will now see that player on the team with a Yellow Triangle next to his name since he was just added and has not been approved yet.
