Just for the rest, when you click on "Register" a paypal "pay now" button appears which will take you to paypal with the correct amount payable. Note that on the same page there is a button print out the usual form to place behind your windscreen. If you miss this, if you try and re-register it won't let you (to save on multiple entries in the database) but you will get the option to print out another of those forms if you missed it the first time.
