Hi,
I have a PDF file on my site that I want to distribute freely but I want to
be able to contact anyone who downloaded it to warn them about mistakes and
new versions and updates etc...

So I need some way to keep their email addresses and someway to prevent them
sharing the link to the PDF file. I want the download to be once-only.

I've seen some sites
- with a form for the user to fill in
- where the user fills in his email address
- and receives a mail
- containing a unique link to the file to download
- and I think the link has a timeout on it somehow.

Can anyone please point me to a script so that I can set up something
similar?

TIA

Joey
