if you go to a blog and put ''tracking''on it it will show how many comments were written after you quit the blog page.
i hope this might answer a little bit of your question and you can always ask to chess.com support: http://support.chess.com/
take care,bye
I keep receiving notices on Chess.com, as well as via email, which say "- You have a new comment to read!". When I go to my home page, I can't find new comments anywhere. According to my "comments" listing... I haven't received a new message in 4 months. I was wondering if either A) I'm doing something wrong and totally overlooking how to check comments, or B) these messages refer to any forum posts I've made which have received a response, and thus don't show up as a comment.
