I haven't heard of it either. Where do I find out about it???
Google Amazon Mechanical Turk. Look up Mturk worker, not requester. Follow the instructions to apply. Just remember this is summertime and the majority of tasks on Mturk come from universities so it's slow through the summer but there are tasks to be completed. At first it will seem like you're only given low paying tasks but most of those can be done quickly. It's best to build up your approved tasks. Once they build up you'll be able to get higher paying tasks. You can always sort through the "hits" by filtering and put "hits that pay .50 and see what you get. Also, some advice, you do need to pay attention and answer honestly, thoughtfully. Hits can be rejected if they believe you didn't do something correctly and having too many rejections will bring your score down. Best advice, be patient, eventually you will be happy with your work and pay. I tend to work Mturk like a outside job. I try to work on it 5-6 hours a day without interruption. If you have any questions I'd be happy to answer them.
One more thing, once you get going it's a good idea to add "Turkopticon" it's an addon for mturk where works can leave reviews about requestors. Once you add it you can check the requester's scores before accepting the hit. Helps a lot. Good luck!
