my experience with PayPal is less than satisfactory. I didn't get any type of confirmation that I had successfully completed the payment process or the registration process. I was just sent back to the page that says Transaction Results with the grey button saying "Make Payment".
If you did not click the final "Make Payment" when it redirected you back to the Rally site, then the payment did not go through. DBK and I will both check to see if yours went through.
Sorry guys - this integration with PayPal's API has been a learning experience for us. I'm going to rewrite the instructions on the Registration page to be more clear about the entire process.
