Notifications and Flags

I have a couple of questions about article comments. First, is it possible to get notifications when someone replies to your post? I sometimes read through a comment section, make a response, read for a bit, then leave it be. It would be nice to get an email when someone replies to one of my comments, though.

Second, is it possible to see why someone flagged your post? I just noticed a flag icon at the bottom of one of my recent comments, and I can't figure out why someone would find it offensive. It hasn't been moderated or anything. I'm just curious about the reasoning behind the flag.
