Replying to Email notifications and A mobile app

Hey NS, lately I've been using NS on my phone more than on my computer because it's convenient to get to an what not. But we all have those times that we're expecting a message or something and when it comes You never know til you check back again, and you might miss the person being online and then a deal potentially falls through and all that good stuff.

SO I want to propose that maybe there be an account setting that would allow you to get email notifications when you get a new message and even when someone replies to a thread you are way into or something of the sort, similar to other forum sites.

I was also thinking maybe for further in the future an NS mobile app that would send push notifications when you get a message and all that good stuff. That way you'll always be up to date and you won't ever miss a deal again!! :D
