You can't do it. Every topic has the same WidgetZone.
But you can add videos to this topic.

Yes, you should add lines in WidgetZones.xml

  <WidgetZone>article_top</WidgetZone>
  <WidgetZone>article_bottom</WidgetZone>

You can use another our plugin NopSocialWidget ,  
widget names article_top and article_bottom.

You can manually add social buttons too.

But NopSocialWidget   adds Open Graph Meta Tags on every pages.
Example.
Your customer likes your page and Facebook takes first image and page title from this page. When you add Open Graph Meta Tags, Facebook takes image and title from Open Graph Meta Tags.

About client's Role, we'll add it.

We'll think and answer you.

What version of NopCommerce are you using?

We tested, it's working.
Open Content edit  page, select Stores tab, and check Limited to stores.

I can't repeat your problem...
I verified all links
Plugins/FoxNetSoft.Articles/Styles/styles.css
They have ~.
Please verify link  in your cshtml-files.

P.S.
I recommend you "make" ONE css file for your site.
Copy css styles from Plugins/FoxNetSoft.Articles/Styles/styles.css to your main css style file.
And remove lines

Html.AddCssFileParts("~/Plugins/FoxNetSoft.Articles/Styles/styles.css");

Your css-style of your themas has a "bug".
You use "rubber design".

I recommend you install FireFox plugin Go-Mobile, enable it and open your site. You should make a window of the browser smaller and smaller...


P.S.
For "rubber design" you should set minimum width for the left column.

Thank you, we'll check it.

IMPORTANT NOTE: There is a known issues with installing new plugins in nopCommerce.
