Here is a first shot at a Intro/How-To Video for Wirite.  We are currently changing the functionality of the site, so the functionality expressed in this video will certainly be different in the upcoming months.  The old site is still up at the Wirite beta page to test out.  Check it out and send any feedback you might have.  There is also a written How-To here.  Thanks so much to Mark Pare and Justin Almeida for making the video!
