Allow user to edit data without logging in

Hey, you guys have been extremely helpful in the past… hopefully you can help this time around as well.

What I need is the ability to create and edit directory listings similar to Craigslist. I want my users to be able to create an entry and upon submission they receive a confirmation email along with a link that when clicked takes them to a page where they can edit and update their document.

If anyone knows of a way to facilitate this process it would be greatly appreciated! Thanks in advance!

nvm. problem solved.
