Shoutbox

All the time I get messages from contacts and for one reason or another, I either forget to read it or I don't hear the sound. I'm sure this happens to most people at some point. It gets very annoying .

So.. A script that, if you haven't opened the conversation after X amount of minutes after receiving a new message, will alert you (toast message, pop-up, etc.).

So, possible? Thoughts please..
