You say "plz" because it's shorter than "please", so I'll say "no", since it's shorter than "yes".
Also, "1337 5P34K" died a long time ago, and I just feel sorry for whoever still uses it.
Koreans, how socially active are you? Because you should know that IQ doesn't mean anything. Sure, you might have a high IQ, but if you just sit on your fat ass lurking through websites, then you aren't smart (I'm not saying you do, I'm just saying in general).
Besides, an IQ really means how fast your brain works, rather than how smart you are. Mine is 143, and I can usually pass my classes asleep (not joking; got a 3.5 without doing any homework or studying).
