Change default font?

I have always created an organizational .dot and instructed all mambers oit the organziation to use that whenever they were preparing material for the organziation.  Actually we had 4.  One each for letters, memos, reports, and Technical Papers and we hamed them as such.  The only issue was enforcement and that took a few weeks but we had 350 odd people using the same templates with little complaint.  About 10 needed assistance as they could not follow our directions for changing the .dot file. 

I discovered taht a number of people were creating .docx files of each of the templates and keeping those in a special folder and whenever the wanted to create a document the just opened the appropirate one and immediately named it and saved it wherever it belonged in their directory structure.
