Hmm, I remember that one, but it must have worked for me. This is not to sign up for Expressions, but for an interview - there are pages of questions to answer in the link first though - well there should be but no questions. Actually can't even blame eBay, I've just literally ticks boxes and got to the end, where its says the page I have requested can't be found, but it does have the name of the research company.
Not going too well for them then!
