PDF expiration date

[bischerboy]

Hi, I would like to add an expiration date to my pdfs so they cannot be opened without a password after say 6 months from when they were created.

Is this possible within Pro 7 or is there any extension anyone knows of?

thanks

You could try PDFill tools, I'm not sure how it works though, I've never used it, apparently it is free.
