Shoutbox

There's no way to change the URL it's poiting to. The AccName and AccDesc are numbers which point to a programmed action in Messenger itself. Those actions determine what site should be opened, you can't change the URL as Messenger simply won't look for an URL in the UIFILEs!

Maybe it's possible by HEX editing the msgsres.dll or msnmsgr.exe in some way, but then still, you can't change that through Plus! skinning.
