The first set of curators will be decided by whoever deploys the Charity DAO. There could be several Charity DAOs with different set of curators.
We have some candidates, but we will figure this out in the coming months.
There will be feedback, but how this looks like depends entirely on the receiver and what he offers in terms of milestones in his smart contract.
There are still a lot of important details which needs to be worked out. We just started and hope to engage the community in order to get valuable feedback.
