What!, you don't have a Ztopic categorizing all threads as they
come in and presenting possible action for you ;)

I am getting more comfortable with the Zope.org way and think I am
being very supportive of the concept in my too long comments.

I think that putting stuff close to the author and giving them good
content management tools is the best way to ensure quality content.

In my message list search yesterday, I found for the first time you
Ztopic comments.  Ztopics looks exactly like what I had in mind.  I have
not looked with any detail at Ztopics but, will try in integrate or
follow others work as soon as I get this first implementation done.

The "click to visit the REAL URL" is exactly the functionality I would
like to see.  Let the content stay with the owner yet have your own
personal Topic descriptor of what is in the content.

Yes, I am struggling with adding Portal Folders.  I like the idea of the
PTK "management screen eliminator" wrapper around addPortalFolder, but
keep getting security access violations.  I think that I am setting the
"Add Folder" permission on the target folder and have tried proxy roles
but, something I am doing is just wrong.

Yes, ZTopics sounds like the solution.  I will revisit the solution
when ZTopics becomes closer to reality.

Thanks for your comments.
