Malleability - the theme for our district! With that thought in mind, anything that is attached to an email, uploaded to the web, or shared with anyone else should be in pdf form. Why? People may not have the program that you used to create the document you are sharing. They might have to have the program to open a document. If you print the document as a pdf then everyone can open the document regardless of type of machine or program. It saves time and frustration. If you do not know how to do this ask one of the members from the technology committee and they would be happy to help.
