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?

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.lovenotesfromabroad.com...
Thanks! I'm not super techy, so I appreciate any help in this.
