You can simplify your code by changing it to this:> on @!*:JOIN:#:notice $nick asl pleaseThe @ means that client who runs the code is opped in channel. I don't see the need for being an op and just send a notice, unless you want to make sure the client, as an op, is able to kick or ban someone. The exclamation mark indicates that it won't be triggered upon your own entry (the client who runs the script). You don't want to ask yourself asl, do you? All in all, this is all you need, really:

on !*:JOIN:#:notice $nick asl please

But either way, you can add @ to be sure the client is opped.
