blog comment block

Permalink
I have the basic setup for my website and didn't do any add-on options. It seems that I should be able to add some html to "reply" to the comments under my blog posts, but I can't seem to figure out how/where to make that happen. Any advice? Or should I just do a blog add-on? If so, which one actually has a reply option to blog comments

In searching online, I've found some examples but can't figure out how to make it happen in Concrete5.

Here is my site if you need ref:www.www.www.lovenotesfromabroad.com......
Thanks! I'm not super techy, so I appreciate any help in this.
