Hi, b11_.
Each Knowledge Base article has a Send Feedback button, which takes you to
the bottom of the article. There you should find buttons for you to vote,
plus a Notepad-like area for you to type in your criticisms or other
comments.
At least, all the recent KB articles have this. Some of the older ones
might not have it.
Which KB article(s) do you think are incorrect? If you mention them here,
we may have some useful comments, too.
