Adding a "comments" section on the website

What we cannot do

   After much research, it seems that I cannot create  a special section for members to add thoughts or comments to the web page. I can add a comment section under a blog or a news page. Comments are submitted and reviewed before publishing to the website.
  
   If people wish to make public comments, the church has a Facebook page https://www.facebook.com/KFallsSDA/
