Sending a document as an attachment is best accomplished by sending it as a PDF with copy an edit protection. It depends really on what you are trying to prevent them from doing with the document as to what level of security you apply.
I just revisited Primo PDF which I`d abandoned in favour of CutePDF when I went over to Vista. You`re quite correct, Primo allows you to add security settings which CutePDF doesn`t so I`m endorsing your recommendation. (And using Primo once again!)
Hi again and thank you for your feed back. I sent a document to somebody by Primo PDF which I downloaded and managed to work out with the help of Marg7, thank you, but the person who has received the document by email has explained to me that when she clicks on the document by email a panel appears and reads; this file does not have a program associated with it for performing this action. Create an association in the folder options panel. Could you please explain to me what and where she goes to, to carry out this action to enable her to read the PDF. thank you.
