Let me explain what you have to do. First of all, you have to give us your email address. Don't worries we're not keeping track of the information you enter bellow. With your exact email address we'll be able to send you the information about your friend(s).

On the next page, we'll give you an internet address which corresponds to the test your friend will try. You'll have to copy this address and paste it in an email you'll send to your friend explaining that you tried this test and it works very well etc... That's all!
