Several of the PDF documents in the Trails End Popcorn Fundraiser Leader's Manual can be customized before they are printed.  These documents are indicated on the menus by this icon:

To customize these documents, open the document in Adobe Acrobat Reader.  Once opened, any field in the document that is underlined can be filled in simply by placing the cursor over the underlined area, clicking with the left mouse button, and then typing your text into the field.

You will not be able to save the edited document.  You must print the document, by clicking on the printer icon at the top of the page, after typing your customizations.
