I have created In design documents which i would like to dsitribute to contacts in a PDF format (they dont have indesign software) with an editable field for them to add their contact details. ...tell me this is possible pelase and how!
At the risk of going into Acrobat forum territory I would add two important points:
1) If, after you created the form, you want to make changes in the original InDesign document, you need to use the Replace command in Acrobat so you don't have to redo the whole form again.
2) When you have finalised the form you need to save the PDF in (Acrobat X) as: File > Save As > Reader Extended PDF > Enable Additional Features. Then users with only Acrobat Reader will be able to both fill in the form, print it and save it.
The forms can be emailed as attachments, put on a CD, whatever. You can add print and save buttons to the form - all kinds of things.
(As usual, Lynda.com has tutorials on Acrobat forms and for those in the UK, Certitec.com has excellent specialised personal training on Acrobat forms.)
That would be replace pages.
