In the old venue you could comment on an article from the knowledge databse, but in the new one you cannot.  I just tried to follow an article called "Adding a Drawer Slide" and I couldn't get it to work because the article failed to mention that, if your library is older than 50, it will not automatically add the new drawer slide to the list in the project wizard and in the drw box tab of the cabinet prompts.  Fortunately, via a help ticket, I discovered you can add it manually to the "List Drawer Slides" variable in the global variables, so I was able to get it working.  If it were possible I would add a comment to notify other users of this situation.
