User Edit history

After months waiting in frustration for Writely/Google to let me in on their 2.0 app, I discovered ZW! And I like it ! Now for the details.
I found that drafting legal documents in groups can be tricky when one or more person are referring to differing versions, comments, etc., leading to timewasting quid pro quos. I think ZW could get more and legitimate attention from the document drafting community including myself once its edit history feature can give the ability to highlight who has brought changes and when- after proper document security features are in place, some people may be ready to do the shift from MS-W... . Also could not agree more with a felllow commenter on the ability to title/describe the revision(again with ID'd comments). I have this image of a version-specific comment blog to the main document's.
In any case please keep it up, I think this is the good future of wordwriting media!
