dubucm,
I am in the middle of re-doing my site that allows this. I have achieved everything so far by just making template changes. You can see a sneak preview at
test.BritishExpats.com. Click on the 'Articles' menu on the top left menu and you can see a few examples in there. Drill down until you see the article come up and there is a rating option, printable, send to friend etc, just like a normal thread.
Like I said, this is all done with templates. The articles are stored as threads. The examples in there already don't allow comments, but the next category I'm working on will.
