i wrote this simple Alias to Akill Selected user . and it works verywell
/f3 /msg operserv akill time 1h *@ $+ $right($address($$1,2),-4) " <Akill Msg>"

BUT:
ON *:JOIN:#: ????
i want to Select Remotly any user joining #channel, exept @ .untill the Second join the same channel.
do i have to use $nick(#channel,1,r,o) ???

What you want is not possible, as when the on join event triggers, a user is never an @ yet. Therefor you cannot exempt channel ops without manually storing the op list.
