GUYS, I JUST NOTICED SOMETHING. I FOUND OUT WHY THE REGISTRATION PROCESS ISN'T WORKING FOR SOME PEOPLE.
Now, I know it isn't the browser itself. I don't know what it was, but after you've signed up and it's not letting you through, don't register again. After looking through the admin panel myself, I can go to the "users and groups" module and take a look at new users who haven't activated their account yet. If you're having trouble, no worries! I'll just activate it for you.
