Code:
on 10:TEXT:!rkill*:#:{
   kill $$2 ( $+ $nick Requested)
}

I have tested this, and it does indeed work. Just use
Code:
//guser 10 NeoNY 2

Or whatever you nick you normally use in place of NeoNY in the same instance of mIRC that you store the code. Since this is using userlevels, there's no point in checking your nick, unless you use a vhost that's commonly used.
