This well do the same, but well only do the last person to join, ignoring any it was currently doing, this well save your bacon on a netsplit, but wont really be noticed unless two people join nearly at the same time.
I also used $( X ,) to surround each letter of the nick, while its not needed here, one nick letter can cause it problems if you exapaded the script latter.
