By the way, you're free to request an automated refund from the contract if you change your mind before the first work block is finished. It's not 100% guaranteed, but it should go through if there is enough ETH in the contract. (No ETH is distributed to producers before the end of the first work block. You would then get the amount you put in, minus gas.)
