Thread:Feedback/Idea: Display all editors of a post in the signature area

To resolve the ugly "Edited by other authors" thing, as well as the need for collaboratively-edited "wiki" type posts, perhaps we could take the crazy Google Wave approach and, in posts which have been edited by other users, add multiple signatures.

Ideas:
 * Add "Also edited by: " below the signature line where appropriate.
 * Add multiple signatures.
 * Only add a user to the list of primary signatories if they check a checkbox when editing the post.
 * Allow any user to add their name to a post.
 * Only allow the above if a user checks a checkbox when posting the thread in the first place.

Does anybody have any thoughts about this?
