Until recently, for whatever reason, when anyone would comment on a post, it wouldn't send me an email notifying me (even though I'd set it to do so). It only started working randomly about a month ago.
To my horror, I noticed that there are LOADS of old posts with a lot of comments and interesting discussions that I've missed out on! I'm going to go back and try to catch up, but in the meantime, if I didn't answer/reply, I wasn't being rude!
Thanks for understanding!
