Question Kunena Discuss--I do not want "Discuss" on every single

I can see your video's, but your site structure is a litte bit messy. 
I suppose the article you are showing in your last video is in the category Bill's blog (14).
So if you want to enable discuss only for articles in this category your plugin settings should be:
 

 

The sites you linked to are using Kunena Forum. I don't see any evidence of Kunena Discuss plugin. As already mentionned in earlier topics, there is the component Kunena Forum, which allows to see the forum component as under your own menu-item Forum, and there is the plugin Kunena Discuss which allows to show a button under certain (or all) Joomla articles to enable visitors (or members) to discuss an article in your forum for the allowed Joomla categories.

You can have a look at my testsite .

This cannot work. LLHOA Website Discussion with ID 34 is not a category, but a section.
If you use the uncategorized Joomla category with ID 2 and want to link to the Kunena category Loud-Boats-65 decibles or more with ID 5, then simply enter 2,5 in the category mapping (image 1). That's all, because I can't imagine, if you ever want to discuss other topics, that you want to use the category “Loud-Boats-65 decibles or more” as the standard for all topics. 
I also recommend that you do not use the uncategorized Joomla category with ID 2, better you create an own category.

You can also use this setting with a standard Kunena category as recommended by @Pinkeltje (image 2). Both work. But then you should also create a separate Kunena category for these discussions.

@rich I think the penny finally dropped.  Blog

I also recommend that you do not use the uncategorized Joomla category with ID 2, better you create an own category. 

Totally agree, saw that (and a lot more as well,  but didn't want to go off-topic as it was already complicated enough. 

Thanks Rich, I'm starting to understand Kuenena Discuss and the Kuenea Forum. It's going to take me some time to let this all sink in. I already created a new category called "general" ID 16

I also created a category for Joomla Articles called General ID 16. See photos attached below. I will have to go get my auto fixed now. Thanks again!

You have entered the Joomla article ID 16 in Deny. Therefore, no discussions will be created between the Joomla category with ID 16 General and the forum default category “Kunena Bill Suggestion Box with ID 37”.
When @Pinkeltje suggested this, the Joomla category with ID 16 did not yet exist.
Either you use the suggestion from my picture (picture 1), or you enter all Joomla category IPs, except IP 16, in the field “Forbidden content categories” (picture 2).
The disadvantage of the setting in image 2 is that every time you create a new Joomla category, you have to enter this ID in the denied list.
