Bulk add all users to group from a trust level?

[jomaxro (Joshua Rosenfeld)]

Wow, blast from the past. Correct, admin/groups/bulk no longer exists. New process:

1. Go to /admin/users/list/member (for trust level 2)
2. Click Export
3. Extract and open the csv file.
4. Copy the username or email column, without the header.
5. Go to /g
6. Click the group you want to add the users to.
7. Click Add Members
8. Paste the list into the Usernames or emails field.
9. Decide if you want the users to be group owners and/or notified.
10. Click Add
