User groups let admins organize users into named sets that reviewers and call admins reference when configuring assignments and restrictions. Create a group once and reuse it across multiple calls.
Open the group after creating it. Click Add User and search by name or email. Select the user and click Add. Repeat for each user. You can also import group members from a CSV file by clicking Import and uploading a file with name and email columns.
Open the group and find the user in the list. Click next to their name to remove them from the group. Removing a user from a group does not delete their account or affect any other permissions.
Groups appear as an option when configuring submission restrictions under Who can submit? in a call's settings. They also appear in the review assignment rules, where admins route submissions to specific reviewer groups. See Call Restrictions and Assign Reviewers for details.
