After form filler completes the form, it is then emailed to the appropriate people using the "email" button. This is working great. It comes thru as a PDF and even those with only the Reader can complete and email the form. The recipients of the form need to add information to the bottom (date received, number assigned, etc.) and email it back to the originator for their files. My problem is that the recipients cannot type on the form after they receive it. How do I resolve this?
