OK PEOPLE LISTEN UP.  WHEN YOU TAKE EITHER GNOMISH OR GOBLIN ENGINEERING YOU SIGN A PLEDGE.  THAT PLEDGE GOES LIKE THIS (FOR GOBLIN):

"SIGN THE PLEDGE, SWEARING TO NIXX SPROCKETSPRING THAT YOU WILL KEEP THE KNOWLEDGE OF GOBLIN ENGINEERING IN ETERNAL SECRECY."

IF YOU DOUBT THAT YOU SIGNED SUCH A DOCUMENT LOOK UP THE QUEST "THE PLEDGE OF SECRECY" AND "NIXX'S PLEDGE OF SECRECY."

IF YOU THINK THAT IT IS STUPID THAT YOU CANNOT SWITCH BETWEEN THE TWO, THEN YOU NEVER SHOULD HAVE SIGNED THE PLEDGE AGREEING TO DO JUST THAT!
