Ok, i've just came across Mailinator which is an odd service but handy. If you dont know what it is then in their words let me tell you.
"Mailinator is a new kind of mail service. The biggest difference is that you don't need to sign up. Any email name you can think of already exists at mailinator.com. Want email@example.com? You got it. Want to be superguy? Happyjoe? fredinpants? No problem. They all already exist just waiting for you to check your mail."
So thats it. You're at a party you don't want to give out your email address so you give out "firstname.lastname@example.org". Go home type in the address and check. Now im sure you can all see the security issue here with common names like email@example.com, but this service isnt meant for "actual" webmail use, from their FAQ:
This sounds pretty insecure. What if I send important emails with sensitive super-secret information in them to mailinator?
Then you are a stupid-head. That isn't what this is for.
So upon figuring this out whats the first thing to do? Check the emails out for firstname.lastname@example.org of course, and then check "andyj". Now its a game. Find a name with a actual message or something in there.
Oh and if you don't know what Google Whack'ing is try this aswell and find "The one".
