Unfortunately that hasn't worked for everyone, me included - I received the the email supposedly with a link to the order page, but the link just took me to the 'register your interest' page again.
Besides which, why do people need to register their interest first? Surely allowing people to place orders is a far simpler way to gauge interest?
Alternatively, give people both options - those who are simply interested can register their interest, and those who want to buy can pre-order (while being warned that deliveries for most people are about 2 months away).
Not sure why Farnell and RS are making it so awkward. I know that order volumes are huge, but both companies have made a real mess of this and seriously ticked off a lot of potential customers (from what I've gleaned on the RPi forum and Farnell's forum).
