How do I include the "Forum Rules" on the registration page?

[slobra]

I'd like to include the "Forum Rules" on the registration page such that the entire registration process is one page. Like this: http://www.webhostingtalk.com/register_new.php

I've been able to get the forum rules on the same page as the rest of the registration info, but I can't figure out how to make the check box functional, such that if you don't check it and try to complete the registration it will direct you to the "you didn't agree to the rules" page. I've been searching but haven't been able to find the answer.

Can someone help? Thanks!
