This came up another thread... seemed like useful information to have here too.

They only have a couple official partnerships so far... one with Cardiac Kids, and the "Education Pool" goes to "Zwischenraum Thurgau" They have mentioned in the recent past that a partnership was in the works, and I just noticed thanks to you that they added a couple new pools on their donate.with.pink site. The new "Humanitarian" one says "We will be revealing our new partner soon! We are extremely excited about this partnership." and the new "Environmental Stewardship" one says "This pool's stakes will be dedicated to helping preserve the environment for our posterity. We are looking for partners, until then the staking rewards will be sent to separate wallets managed by the Pinkcoin team until a partner is found, at which point they will take over ownership of the wallets."

The other pools are as follows:
Relief - "Every coin minted on this address will be sent to help those in need."
Administrative - "This wallet will remain building until a voting system is put inplace so the community can choose which projects funding goes to. This pool's stakes will be dedicated to amp up marketing and technology developments of the Pinkcoin network."

and within the "Rain Forest"
Rain Cloud: "It is always raining PINK on those supporting the network by staking. Every coin minted by the Rain Cloud will be divided evenly across each address that has staked within the last 24 hours."
Elder Tree: "The elder tree supports the whole forest with seeds. Every stake from the Elder Tree goes to a random address supporting the network.
Acorns: "A forest must nourish even the smallest of acorns to survive. Every time coins are minted on this address, they are sent to the smallest wallets on the network."
