Try this, although it may get people that are using methods other than Mibbit.
on *:join:#my_channel:{
if new_user* iswm $nick {
.msg $nick Please change your nick using /nick <newnick>
.msg $nick Replacing <newnick> with the nick you wish to use
}
}
on *:nick:{
if new_user* iswm $newnick {
.msg $nick Please change your nick using /nick <newnick>
.msg $nick Replacing <newnick> with the nick you wish to use
}
}
I also included code that gives the same message if they change their nick to another new_user nick, or if they try to use a registered nick that isn't there's and the network/nick service, changes it.
