That is my #1 desired feature as well, so it is definitely being planned. Lots of suggestions have come up around notification methods, but I'm thinking that email is the right way to go for this... any thoughts?

 

I have only really seen it done through email.  I would do email as a minimum.   I prefer the sites that not only tell you there is a message, but also give you the post in the body of the email.
