After I create my newsletter in Pages I export as a pdf file. I open the doc using Acrobat X Pro where I then add a text box (tools, forms, edit, add text box). It works perfect, BUT if I find an error in the doc and want to go back and repeat the process with the correction, I will lose the info on one of the pages. This same thing happens if I edit the doc and change the text, correcting the error on the original pdf file. Any time I change anything on this pdf file after I have inserted the text box, I lose all the text on one of the pages.
