From the Dashboard, Select "Club Management" followed by "Roster Builder"
Select the event that your teams are registered to, and select which teams you want to build rosters for. Then click "Submit".
Once on the "Roster Building" page. There are two ways you can assign a player to a team. First, you can use the hairpin to drag the player to the team that they should be rostered to.
Option 2: You can check the check marks next to the players name and click the "Add to Team" button for the particular team. This is the better method if you are attempting to bulk add players to the team roster.
Any players on the team with a Yellow Triangle next to their name will need to have their roster spot approved by the governing body. That is almost always what will happen during this process. Players on the team with green checkmarks signify they have been approved by the event.
