i clicked on the banner ad to send a friend the link and noticed that 2 of the free credits were for signing up for the RR email update. since 2 more credits and my future scheduled travel will give me 16 credits, i was excited. unfortunately, after entering my info and hitting submit, i get an error message saying the site was temporarily unavailable.

Update: after several tries, i was finally able to sign up. hope i don't have this much trouble getting the 2 RR credits!
