Try this code
on !*:join:#: { 
 if ($nick == Nick1) { noop $tip($nick,Join,$nick joined $chan,5,,,echo,$wid) }
 elseif ($nick == Nick2) { noop $tip($nick,Join,$nick joined $chan,5,,,echo,$wid) }

Replace Nick1 with any nick, same goes for Nick2, you can remove the second nick or add more users if you want to, just copy the last line and replace the Nick2 part. This will open a small window in the right corner of your screen.

if ($me != tired) { return } | else { echo -a Get a pot of coffee now $+($me,.) }
