TSM is short for tradeskillmaster. It is the most powerful gold making addon in the game with an accompanying desktop app and premium service. I suggest checking their recommended guides section to get started. It is the only reason I am able to make as much gold as I do. I use it to pay for 2 accounts using token and I am currently sitting at about 12 million gold total.
