Most people hate giving out their email address to a website to access a portion of a website. In most of these situations, you have to give out a real email address because the website will send a confirmation email that you will have to access. Some people have set up a separate email address just to deal with this issue.
A different, but very useful, solution comes our way from 10 Minute Mail. 10 Minute Mail provides you with an email address that automatically expires after 10 minutes. During the 10 minutes you can access the email that arrives at the address. This allows you sufficient time to respond to a verification email.
Once you do that, however, you need not worry about having provided that email address and you don’t have to worry about wading through the spam created for that address. According to the operator of the website, he gets between 20,000 and 30,000 emails a day, all addressed to expired email accounts. Let his server deal with that spam instead of yours.
