When someone is tagged as member of a group, they will automatically gain access to all boards, which were shared with that group. This simplifies both sharing new boards with people and adding new users to the account.
Simply specify which group or groups someone belongs to, and they will see those group's boards automatically.
To create a user group, go to the People tab, and click to edit a user.
Add a new group name under Groups and save changes.
All groups that were created in this way become available to pick in any user's Groups drop-down menu. So, you only need to type a group name when you're creating it - existing groups can be picked from the list.
When you then go to share a board or folder with people, you'll have the option to share it with a whole group in one go. Sharing options for a group remain the same, as for individuals: you are still in control over if a group gets full, read-only or custom access to a board or folder.
If a person is in a group, that you've shared a board with, you no longer have to check their name for individual access. Of course, other individual users can still be given access permissions to a board shared with a group.
Please note, that access rights given to someone through groups sum up, and that individual user rights will always override those gained through being part of a group.
Example: It's possible for you to be in group A and B, and for group A to have rights to only create tasks on a specific board, and for group B to have rights to only delete tasks on that board. So, by summing these up, on a board shared with groups A and B, you will be able to both create and delete tasks.
Still, if an admin edits your individual access rights for this specific board, and gives you full access - you will be able to perform all possible board actions.
And likewise, when your group rights give you full access to a board, it is still possible for an admin to limit your privileges on a board, by editing your individual rights.
Please note, User Groups are only available to the Enterprise plan subscribers. You can manage your service plan in Account Administration - Plan & Billing details.
