Registration
I didn't really make it clear when I revamped the site initially
that I had merged the forum registration with the number submission
registration.
In any case, to be clear, if you want to submit numbers or post to
the forums you register in the same place. When your registration
is complete you can test it out by signing into the forums. Then
when you're sure it's working you can submit numbers using the same
login information. You'll have to login again though because the
two parts of the site don't share cookies.
