Ok so the way it's done here: https://forum.getmonero.org/8/funding-required/325/monero-website-and-core-translation is wrong.
The person pitching the idea shouldn't be the one putting it in funding required, because how do they know how much it will cost? It's NOT a bounty, it's funding a specific thing. I can't go create a Kickstarter that says "put fluffypony on the moon" and tries to raise $50 000 because that's what I think it'll cost, nobody would back that.
I also think that something like "exchange development" shouldn't be crowd funded using this system - the exchange operator is going to make money, and the crowd funders are going to be paying for the development, seems a bit unfair:) Exchanges will add XMR markets as and when they see fit.
What I encourage you to do is find people who are willing to DO those tasks, and get them to pitch a cost, timeline, availability, milestones, etc. in the thread for that idea. Once we have someone that is willing and able to take on the task we can move it to funding required.
