create / edit intranet

[Lynne Desrochers]

I created our "intranet" ages ago, using word 2003 and saving it as a web page. I wanted to revamp it, so I created a new main page using word 2010. When i went to save as a web page it made it an .mhtml file type? What is that and is there a way to save a 2010 document as an .html?  I'm also open to suggestions on what you use to create your intranet.  Ours is nothing fancy, just a bunch of hyperlinks to different things on the shared drive.
Thank you!

when "Saving As" in Word 2010, the next option down under "Single File Web Page" is "Web Page" which is html.  See attached.
