If they published this news, it means the new forum is almost done and most of us obviously use working emails.
Just hope multiple account user for signature campaign/sell still have their working emails

Maybe we can expect better security such as 2FA and working secret question.
2FA is only for people who can't keep their passwords safe. It should be optional. I don't see a plus in requiring a working e-mail address. It reduces privacy.
I fear the new forum will make intensive use of JavaScript, which is a nightmare for any speed / security oriented user.
