Creating a form in InDesign

Hi,

I have several documents set up in InDesign as templates.

My staff and volunteers will open the document, edit only a couple of items and print it out.

I would like to be able to have them use Acrobat Reader to edit the documents while (hopefully) maintaining the style (font style, etc).

See the items with the purple background in the example.

Most of the volunteers will have a PC.

Any ideas on how I should set this up and save it?

Thanks,

Matt
