Well on my forum, when you change your email, you must authenticate it. Now the email does send to the person; however, the little notice vB gives that tells you that you must authenticate said email is no longer showing. It simply allows them to change it then it goes right back to their profile and doesn't notify them to check their email. Now I'm getting all of these "Contact Us" emails with people telling me they can't post on the forums and I have to manually tell them to click the link sent to auth their new email.
