what does one do to earn cash?
Always be ready to perform the task finmail.com offers. or rather be ready to submit solutions to finmail. your submission doesn't necessarily mean you will get paid. it is only after judgement that you get paid. After the judgement, if your work is validated as a good one by finmail, if your work is helpful, or qualified to meet up the standard according to the judgment norms, then, that will be when finmail pays you.
To the best of my knowledge, I think Finmail is a web site where people get to express or show their various talent or skills for jobs which payment are offered for each validated delivery.
