I've seen this sort of coding implemented on other sites, and I like it. It's very simple, just something to brighten someone else's day, like a 'Like' on Facebook.

My idea is to use pebbles. There'd be a tiny colored pebble (blue, red, green, etc.) that would appear either in your inbox or den. If you clicked on the pebble, you'd see the message that the other player sent, and maybe their ID number.

So what do you, fellow Liodeners, think? I'm completely open to critiques or suggestions.
