Honestly you guys, it was a joke. Come on. It wasn't even rudely sarcastic. There's a difference between being rudely sarcastic and just plain sarcasm. Mazz even put in a link to answer the OP's question! If he was really trying to be rude and sarcastic and what not, he wouldn't have included the link.
I even chuckled when I first read the OP. Granted, I already knew the answer... No, it's not polite to laugh at the OP, but Mazzle wasn't making fun of the OP (airdragon was
). Mazzle was just making light of the situation.
Yeah, maybe a simple yes or no would have sufficed, but doesn't anyone have a sense of humor anymore?
