title: Adding a custom file format to the Word 2007 save as dialog
body: <p>I want to add the option to export to a new file format in Word 2007. Ideally it would be nice if the option could be another file format in the Word 2007 Save As dialog that the user could select in the file format dropdown box.</p>
  
  <p>Although I have a lot of .NET experience I haven't done much development for MS Office. At a high level what should I look at to add another save as format to Word 2007 using .NET?</p>
