I will test.

But here's a serious question.

If you contribute "money" (which is value, energy), how is that not "fair"?

You realize that money in itself isn't evil right? You realize also some people don't have time to contribute to your project by the means you want, but when they want to buy something they give you money in exchange.

You're trying to make a "fair" distribution. Good luck with that, it will never be completely fair. But you're already stumbled upon these problems yourself...
