1. Go to AdminCP > Settings > Options > Human Verification Options, and check "Search".
2. Go to AdminCP > Usergroups, edit the desired usergroup you want the Captcha to be applied to.
3. Set "Require Human Verification on Configured Actions" to Yes.
4. Repeat Steps 2 and 3 for other usergroups as necessary.
