When trying to register, I fill out a username, email, and password (copy/pasted from a password manager, so no chance of mistyping). I complete the captcha, check the consent box, click register, and... nothing. Page refreshes, but there's no errors displayed or anything. I've tried resetting my password, but I never get an email for that (I'm assuming because creating my account failed). I've tried different browsers, mobile and desktop, addblockers on and off, and get the same result every time.
I'm not sure where the guys are right now or if you still having that issue but it is likely related to the CDN news from a few days ago, which seems to be the cause for some other issues too.
I did end up disabling registration due to spam. I can either open them up at a time you’re free to try again or I can manually create an account for you.
