Actually, noob is a very commom way to spell newbie if you''ve ever played any online games. You may want to check your grammar as well. You asked a question and put a period at the end. Your sentence "Learn to spell then come ask for help." is grammatically incorrect also. What''s the point of pointing this out I wonder? NOTHING. Now for a serious post...

By the way, if anyone''s wondering what this is about, there was a flame post that I deleted while this was being written. Apologies for any confusion.
