Even if it is just a thank you, I wish there was the ability to send a reply when someone posts a comment for you in the forum comments.
I just like to acknowledge when someone has made a comment but writing a private message feels like a bit much.
For example, you write something personal and someone posts a hug in your forum comments. I appreciate it but writing a private message to say "thanks for the hug" seems too much. A reply option for the forum comments would work well.
You want to let the person know you appreciate the comment
And because I didn't know where forum comments were, it is on the bottom left hand side of the post represented by the star. That's how you post a comment for someone. (I didn't know this for the longest time)
