When sending out text documents to students, be certain students are able to access them.  If you want to send say a Word document (.doc), create it and then convert it to a PDF document.  To do this, go to “Save As” and change the document type to PDF.  All .pdf documents can be read using the free Adobe Reader software.  Doing this will ensure that all of your students can see the document and that the document can’t easily be changed.
