Only team captains and co-captains can remove players from the team's roster.
To start, click on your team name in the top left corner to access your Team Dashboard. Next, under Settings, click on the Manage Team Members tab
Next, on the Player you'd like to remove or edit, click on the 3 small dots on the right side of their name and select Delete Player:
Note: if the Player you are deleting has existing supporters the Player will be moved into a "Deleted players" group and listed at the bottom of the player list. They will not however be counted towards splits on the budget app.
