Well I envisioned it as being like the current Copper Membership where you pay to the forum and the rank is automatically credited to you, and then every month or quarter or whatever the forum donates it to charity. You could have a public vote on where the money goes or something. I suppose you could also personally donate it to a charity of your choosing but that would require manual verification by staff somehow to make sure people don't cheat it. Signing a message from the address you just used would work but staff will still have to verify that unless you could automate the verification somehow.
