Would it be really difficult to be notified when there is/are comments on your answers?

There isn't a limit on the number of comments we can give every day so that could be a nightmare. Comments can be deleted too and added on any question even when a best answer was selected so you could get 51 emails about comments but there are really only 4 -5 of them and so many would be asking ' Where did my comments go..it said I had x number but only x number shows' like now with answers.

I imagine it would be hard to program that and can't imagine yahoo would bother trying..

yahoo doesnt notify people when they get comments.

It would not be easy programing. Since comments are not limited, your mailbox would be filled with spam emails of they had notifications. You just have to keep track of where you might get comments.
