Viewing Safari Form History

I am useing Version 5.1.7 (6534.57.2) of Safari.

I signed up for a website on August 8, 2012 and I can't remember the email address I used to sign up. I thought I had my form history saved so that when I start to type, the autofill finishes it but I guess it doesn't work for me.

Is there anyway that I can find the email address I used by going through Safari's settings?

I hope this question makes sense.

Also, where can I view the screen shots that Safari takes for the browing history view?
