How do you facebook id hack?

You can only get someone elses email address if they have it posted in their Info tab on their Profile Page :)

we can tag pics

Just Go to youcanhack.co.uk and type any email adress in the given bar and click on the hack button

because if u gave some body your e-mail address then they can use it to hak in your facebook.
