Users post a question and a suggested value between $5 and $250 that they will pay for the answer. Users also can provide a tip to the researcher who answers their question. If a user is not satisfied with an answer, a refund will be provided, Moore said. The site will not write an essay for a student or complete a homework assignment, she added. It also will not provide personal details about a living person.

Unlike Yahoo Answers, which allows users to post answers to questions for free, "a paid answer service not only produces better answers, it also attracts better questions," Moore said.
