I completely forgot about this, I have no idea how.
But, when it says “we temporarily limit what new users can do” I believe there should be a link directly to how to join the forum ie.
“For safety reasons, we temporily limit what new users can do.
Start reading and in no time you’ll join the forum completely, you can read more here.
Over time, you’ll gain new abilites (and badges) as we get to know you”
