Question about replies to comments.

I finally read through your post (sorry it took me so long!), and got there because under my name it said "1 new message" or something like that. I clicked on my username to check it out like you suggested, and noticed that people had replied to some of the comments I made. Are we supposed to get notifications of replies (as well as direct messages), or is that intentionally not a feature yet?

(Sorry if this has been answered elsewhere)
