Until now there has been no way to give people comment-only access to a document in Google Docs. That’s a problem because you may want feedback on a document without letting someone actually change it. According to this Google Docs blog post, Google Docs accounts will start gaining the option of sharing a document with people in such a way that all they can do is add a comment. You can even set public documents such that anyone can comment. With this change, Google Docs becomes an even more valuable collaboration tool — there’s almost no reason to mail Word documents around for comment any more. follow link
