If you only use 1 nick then change the line to this:
if ($me != Nick1) {

Easy fix

I upgraded !Slang so it now has flood protection.
I don\'t think it was probably a problem really but its there now.

Thanks napa182.
I\'d like to clarify one point. If you look up a word and see more than 1 result returned you can look up each and every result one at a time.
For example if you type !Slang 1 bed ... you will see:

(1/8)-bed Definition a matress on a stand or on the floor (lol) that has a blanket and pillows on it and u got to sleep on it coz sleep is so good Example im gonna go hit the sac... then im gonna go to bed ;) Author flash URL http://www.urbandictionary.com/define.php?term=bed&defid=778262 [782]

That 8 means there are 8 entries for bed. To see the next result you can type !Slang 2 bed all the way up to !slang 8 bed. Some Slang words have hundreds of entries. They are ranked by most votes.
Some entries are quite long and will flood ur channel. Not much I can do about that really. lol
Thanks,

This script is to stop your registered nick from ever changing to any nick besides the nicks you list in the IF code block. If you ping out it will auto ghost, release and recover your nick, change you back to your main nick and identify you.
