While at the Plone Symposium, I started working on a help system for
Plone sites. It's aimed at helping site administrators create help
documents (using PloneHelpCenter, standard Documents, or any other
content type they want). This product adds a straightforward,
actions-registry for these help items, so they can appear in the UI in
a portlet (or, possibly, other places) for the users.

I've uploadeded it to the SVN collective as "PloneHelpRegistry".  It
works, but needs tests and perhaps some UI cleanup before I think it's
deployable.

Information and downloads at: 

  http://plone.org/products/plonehelpregistry.

I also have an ambitious hope for a Plone Control Panel version of the
registry for it, so that end administrators can associate help items
to places in their sites without having to use the ZMI or know about
TALES. This part is mocked-up, but not functional, and is explained in
the TODO.

It's a bit similar to, but very different from Andy's PopupHelp, and
would, for many sites, be useful in conjunction with that.  It takes a
different approach to how help should be added, and how the connection
to which help items should appear should be specified. I've detailed
the differences in the products README.

Any advice/feedback on the idea/UI would be great.

Thanks!
