Shoutbox

I believe this has appeared on the forums before.
IIRC, it didn't get very far before it was turned down, as it would mean skinning Plus, which (like skinning Messenger) is illegal.

I can think of a different way of doing it though: Plus could get Messenger itself to display the toast, that way it would be the correct colour. However, I'm not sure Messenger provides a method to do this. Then again, with WinMsg, Plus toasts look like WinMsg toasts, and with MSNMsg, Plus toasts look like MSNMsg toasts...

In other words, speak to Patchou.
