Not sure if this will help anyone, but I registered on here and was waiting for the email to come through to verify my email address. I figured maybe it was taking a while because the server was getting hammered. Turns out it was in my junk folder. So if you’re newly registered and haven’t received that email yet, I would check there.
Sometimes the approval emails get stuck in SPAM. You can try logging in as you might have been approved already and just never got the email.
