The code is working fine for me:
Code:
on $*:action:$(/\bslaps\b.*\b\Q $+ $replacecs($me,\E,\E\\E\Q) $+ \E\b/iS):#:{
  msg # UNINSTALLRO, UNINSTALLRO～ UNI UNINSTALLRO, UNI UNINSTALLRO ～♪
}
I'm not certain why it fails on you. The only thing I can think of is to make sure your remote is on by entering: /remote on

What color of text do you want it to appear?
