This sites are indeed cool, check them.

The first allows you to see lots of sites without forcing you register using a premade dummy account.

This one instead is a free, setup free, email receiver. If you need register to a site that ask you the email for some confirmation and you are afraid of being spammed later, just use a @dodgeit.com address, the server will receive it and you'll can read with easy keeping your real address private.
