Attribute Wiki changes

When someone edits the wiki, there is no trace of it having been edited - in other words, if I post a page, and you come along and delete what I've written and write some crazy manifesto, your manifesto is attributed to me. Is there any way to highlight or otherwise distinguish content submitted by different users? Or to make "changes" visible, with the proper attribution to each successive author?

Philosophically, wiki pages shouldn't show a single author anyway. So we'll disable showing the creator for that content type.

It would be nice to add a de-emphasized list of all authors on a particular piece of content. This can be created by querying the revisions table, as long as the content type is set up correctly to use revisions. WSF2008 needs this also. A module that can do this and provide the list at the top of the content, below the content, or as a block would be fantastic. I would think something like it exists.

And then, of course, there needs to be a link to the diff module's output. This could (in principle) be integrated with the list of authors to provide links to the changes made by each person.

The link to the diffs is done as a tab at the top of the content, and can be placed elsewhere in the form node/#nid/revisions, for instance: http://agaricdesign.com/node/780/revisions

Resolution

1. Disable editor name (or rather content creator name - this is done in admin/build/themes/ )
2. Enable diff module and anonymous view of revisions
3. Talk to client about, and look for and possibly build, a module to display all people who have edited a node
