Publish now has the content that each article has a single author.

We're doing some applications that are more like "publishing" than "creating an article on a web site" and we'd like to be able to include that in our pages.  For example, we'd like for the "authorship" concept to be expanded to include multiple authors, so that multiple author names would appear and would also go to multiple StoryFeeds (assuming that you implement that suggestion).

It would also be nice if "authors" could also be specified and not have to be registered users of the site.

I would have no objection, either, if there were a way of specifying an "editor" of an article.
