Hi!

Tiki CMS/Groupware is very well suited for what you describe. Tiki can
use many databases (including mysql) thanks the ADOdb abstraction layer.
http://freshmeat.net/projects/tiki/

Tiki offers comments below the wiki page. The comments are threaded.
Alternatively, you can also activate "discuss this page". In which case,
users are can discuss this page in the forums.
http://tikiwiki.org/CommentDoc

Groups & permissions are very flexible. You could have one group of
people only allowed to comment whilst another could also edit the wiki
pages. http://tikiwiki.org/PermissionAdmin

Tiki also offers structures which permits you to order the pages into a
book with table of content. http://tikiwiki.org/StructureDoc

You can also upload images. You can also use the JgraphPad drawing
applet to edit illustrations. Ex.: This can be useful to add notes &
diagrams to a screenshots. http://tikiwiki.org/JgraphPadDoc

We have just released version 1.7.6 Version 1.8.1 will be out any day now.

Best regards,

M ;-)
