I signed someone up for the promo and get this "rejection" message:

"We're Sorry

You have already played in The DraftDay $5
Challenge. Each player gets one free
Challenge before they must invite new
friends in order to get more free Challenges.

Click continue to invite your friends to DraftDay."

Can someone explain this in more detail and point me to the section on the site where it shows the rules on the $5 challenge promo that shows this "rule". Its a bit frustrating to get someone to sign up only to find out the $5 challenge promo is somehow blocked?

Hi Slinky:

The $5 Challenge is meant to encourage new signups at DD. Each person is permitted to play 1 free draft as well as an unlimited number of $5 Challenges (as long as the opponents are new signups).

If you believe that the rejection message was received in error, please email us at support@draftday.com and we'd be happy to look further into the matter.

I'm sorry for any confusion and the inconvenience.
