/scp/settings.php?t=tickets Halfway down "Human Verification" is a checkbox that lets you turn it on.Hmm, that's for new tickets, not the registration page (I've never used the User Registration features before.. doh). You'd think there would be one aye. You'd have to manually add it, editing account.php to add the serverside checking processing, likely login.php as well.Then to add the actual captcha image and inputs to the forms, you'd need to edit:/include/client/login.inc.php and /include/client/register.inc.phpGood idea mate, maybe suggest it on Github.Someone has: https://github.com/osTicket/osTicket/issues/3597 (for login)https://github.com/osTicket/osTicket/issues/864 (for registration).. it was closed last year, but not fixed.. hmm.Maybe we need to add it!
