Review our webapp - Apollo
Vandy_Travis: You should work on your copy on the main page.  It isn't clear exactly what the app does.  You discuss what it is (a way to get comments from another group), but I had trouble trying to picture exactly how it works.  As near I can tell, I work on a doc (image, whatever), then can share it with other people who can comment on it, within a protected area of a site.  That isn't too clear from the front page.
