Getting emails about responses to comments?

This is a simple enough question, although I don't know how feasible implementation would be on the backend. How likely is it that we're going to have the option to receive emails when people respond to our comments? I'm loving the comment system here, but it feels kind of unwieldy to have to go to my profile and then check my most recent activity in order to ensure that I haven't missed the opportunity to engage the members here in a cool conversation.
