Shoutbox

the "check your inbox" button actually doesn't throw an event in scripts, and can't (easily) be manipulated with scripts...

with a normal plugin you can subclass events meaning, you intercept the button click, and execute the code, and send the 'click' on it's normal path...
With scripts you can't do this though, so the only thing I can think of, is make your own button... and put it over the inbox button, but that isn't that easy either...

StuffPlug is going to have this feature (open in default browser) but isn't out yet (for WLM)

If you need any more help, just ask... that's what we're here for
