nice, i had no idea about this. if anyone would like to share similar thoughts, here's the message i just wrote, obviously you can edit it any way you like:
Hi! As a veteran Masters worker, I would really appreciate if you could somehow display or have installed the Automatic Approval time on the worker site. As a worker who relies on MTurk for income, it is absolutely necessary to know when I will be paid for work completed. It is an important factor in accepting and completing work. Although workers are (correctly, in my opinion) classified as general contractors for MTurk, it is commonplace and expected in other industries and professions that contractors performing work are made aware of and are able to acknowledge the timeframe in which they can expect payment for that work. Without knowing when payment for work completed will be rendered (which could be as little as 1 minute or as long as 30 days), it is impossible to judge what type of work is worth completing depending on the individual worker's needs at that time. I urge you to add Automatic Approval time to the HITs on the new worker site. It is absolutely imperative for the continued integrity of the worker-requester relationship. Thank you for accepting feedback.
