You also need to be aware that they may not link everyone who has registered through your mail. I followed your link and then sent the mail out to a number of friends. I immediatley had three acceptances and then they stopped, even though a lot of friends mailed me to say they had registered. To double check, I sent the mail to two other emails addresses that I own, registered and then went to check - They had not registered them on their site. Hope this makes sense. Cheers Gadget
