- Require the registration to be manually approved by an admin
- Block this registration
- Add to User group
Anyway, to do that I have to manually approve all those users and then manually add the approved users to that restricted user group. Fortunately there is the Batch Update option to set the secondary user group but I still cant use the Batch Update to approve all.
BTW, if Batch Update allowed controlling User State, that would work as well.
