Using Leafdoc's service
You're Pam, someone who's got a home insurance document that you want to store in a searchable format. We will assume this has been scanned and is now a TIF image (TIF can store multiple images in one file - ideal for keeping all the pages of one document together), stored somewhere on a computer or network.
Pam opens her email application and attaches her TIF to a new mail (as a Windows user, she knows she can also locate the scanned image in a folder, directory or library on her computer, right-click it, select 'Send To' and then 'Mail recipient...'). She addresses the email to Leafdoc. Pam's already stored the Leafdoc email address in her addressbook so she just types in a few characters and her software auto-completes the rest for her but if this was the first time she was using this, she would lookup the correct email address to use.
All she needs to do now is add her PIN code; a four-character 'password' that we use to confirm this really is Pam and that she intended to send this to us for conversion. This goes in the subject line AFTER any other text (or as the only text, we don't mind). Any text in the body of her email can remain; Leafdoc won't touch or change it in any way.
When we send the returning email to Pam, we'll remove the PIN code she entered but leave anything else we find in the subject line. This means that Pam can still search on emails by title or subject, knowing the text will be just as it was.
