This tab will allow you to quickly assign multiple users to a selected group.

This page was created to make the process of managing users/groups within the site collection more manageable. When a user is selected, the available groups are displayed on the left and the groups that the user is currently a member of will show on the right. Selecting multiple groups is supported.

This tab allows us to copy the members from the "Source" group over to the "Target" group. It's not a problem if any of the users already exist in the destination group. Note: This is a onetime operation so any additional members added to the Source group will not automatically be added to the destination group. You will need to repeat this process.
