Can we reply to comments made?

Just wondering if we can reply to comments made. I did not see anyway how so I was unsure if I was missing something.

This is something that's been sitting on our to-do list for a long time. However, we haven't yet found a good solution that wouldn't slow down our loading speed too much.

As of now, we simply answer by addressing the person in our comment, like, @chefkeem 

Ok good to know - thanks ;0)
