When you are finished working with a team member, or if you want to remove a team member from your account for other reasons, you can easily do so in your account settings in the Team Members area.
Click on the three dots at the end of the team member's line and select Delete.
Confirm the question if you want to delete the user with the button Delete.
The former team member will then receive one last e-mail confirming that he/she no longer has access to your picdrop account. All uploaded data, created galleries, selections, color flags etc. of the team member will of course remain in your picdrop account.
