I think that all donations should be private from board members. It may not be possible to hide your identity from Alex, who actually recieves the donation, but I don't see any reason why board members need to know how much anyone has given. By saying, "so and so is a gold supporter," this creates a heirarchy of poeple who have donated a lot of money, people who have donated a little bit of money, and people who haven't donated anything (although they might have done so anonymously). That will put pressure on people to donate money and will ruin the friendly atmosphere of the board. I do not object to asking for donations to help with improvements to the board, but if it's going to turn into a place where people's status is decided based on how much money they have given, it won't be a very supportive or friendly place any more.
