Chixor got me into it in one of her journals. It's a service where people text in questions from their cell phones on pretty much any subject you can come up with.... sports scores, celebrity gossip, astronomy, etc. We answer the questions and text it back to them. I work as an expeditor under the username absolut3zero. Basically, I get the questions first, check the spelling, check to see what subject category it should be filed as, then send it to the guides. The guides actually search for the answers and send them back to the customer.
Like I said, the pay rather sucks. Expiditors get $.03 per query. Of course, once you get the hang of it, a query only takes 10-30 seconds to answer. Mostly I just do it cause I can work any amount of hours I want, any time I want, from home.
