WordPress Plugin – SitePoint

Hello, I am curious to know any plugins for WordPress that I
can use to build my “Comments” and “UI Cards Sections” that
pull information in my Authors page.

Blog Page with Comments:

Authors Page with Archive UI Cards:

I can’t name a specific plugin, but the functionality is pretty normal. i.e. “get recent comments” and “get some metadata” or whatever.

You just have to give it your heavy styling.

Have you searched the plugin directory? A search for “recent comments” has some promising stuff. What you probably want is a shortcode to drop wherever needed. Otherwise it will have to use the API and be added to your theme template files.
