#NickDetect end 

that was my try and I failed

Wouldn't that issue lay within Vincula's msn.decode alias?

I don't know

bonty, i have this name checker, and i dont remember that it works with $msn.decode in the 1st place. remove the decode and everything will be just fine

coz then the script will msg the $nick to room, wich will be automatically decoded when displayed
