Here’s a new feature some people might find userful: You can now bulk add people by email address or username to a group. Simply go to Groups > Bulk Add to Group in the admin section:
This is useful in the case where you have many existing users who need to be added to a new group. Remember: if you are adding new users to the site, our invite feature allows you to import a group at that time. If the users don’t exist that is the preferable route to take.
