Hi Dave, thanks for the answer. You just gave me the criteria for putting files in acs-subsite. Will change that then and put it under /register/restore-bounce (in line with /register/restore-user).
As for your question, the user himself is able to restore it, as they are getting a notification that their e-mail is bouncing with a link to enable it again (in case the email stopped bouncing).
Admins should be able to see all bouncing users (probably subsite, but I guess site-wide is even better) and unbounce them manually (in case the user wrote a manual e-mail, the admin changes the e-mail address to reflect the new one or whatever the reason).
