End User Manual and SharePoint Wiki

[Stuart Burnfield]

Is there any sort of wiki tool that would let Jim's customers annotate 
but not edit the content? If the text can't be changed by the public but 
they do have the ability to attach comments or footnotes, that might be 
manageable.

Wikipedia has a Discussion page for each article--does anyone know if 
Wikimedia would let Jim lock the help articles but open the discussion 
pages for editing?
