I think you have to first sign up to be invited on the list...
You're correct, BriGuy20.
Shiznaught, allow me to quote myself, from a previous thread on this subject. ;)
...if you are interested in being considered, please do fill out the application here: [google.com...] Then, if and when the program expands, we'll contact you with your invitation.

Is this just a straight referral, or is there an incentive from Google to get people to sign up? (Like a $5 credit to new AdWords customers to get them started?)
I don't expect Google to give, give, give, but it seems like it would be easier to get people to sign up if they could see how well the program would work for them (I was sold after watching my logs the first two days), and it would be easier to refer people by offering them the $5 credit for new accounts.
just an idea...
