I like watching the world burn.

newgui "vanityspy" [
    looplist i (listclients) [
        if (!=s (getclientvanity $i) "" [
            guilist [
                guistrut 2
                guitext (getclientname $i)
            ]
            guistrut 0.5 1
            guitext (getclientvanity $i)
            guistrut 1 1
        ]
    ]
]

Hey, thanks for your "support/contributions". Haha. :D
I know its easy to spy out; it's only for silence chat if 2 player has one topic and don't want to annoy the other player.

Btw, can I add your script to mine? Would be cool.
