Hi, Dan. If we go to
http://chopshop166.com/drupal/mayhem, it says nothing about registration not yet being open. And, if we click the "Click HERE to register" on that page, we're brought to a working registration page at
http://www.chopshop166.com/drupal/team_registration (although there are hints that the page is antique).
Will all registrations before 5:00 PM on Monday April 20th, 2015 be discarded? If so, then you should probably make that clear on one of the above pages.
Thanks,
Dan
