as a payment sheet
?

it's just a suggestion though.

Answer 1

Note that Open Study is a free studying/learning/helping site.
Most of the users here, does not come here and help to earn money, they get a much more valuable thing :\(\: \large knowledge. \)
by both helping and by getting helped.

Also such system can be abused easily, and with large audience on OS, it would be very difficult to control users who would just give out answers to earn money. That will defeat the whole purpose of learning.
