Thank you, again. I will check the plugin option. Yes, the site has multiple authors so the right sidebar on each article must be customized to the author of that article. Such widgets already exist in many cases.
A second question: If we choose “content left” (sidebar right) does that apply to all pages on the site other than the home page, or can that be customized by navigation section? i.e. does “content left” put the sidebar right on all pages under different sections in the main nav?
