I was under the impression that the $ donated was to be saved to help pay for a new server.

I suppose it does not matter exactly, if that money was used for other things related to brainking, and then use money collected from memberships, for example, to pay for a new server.

Maybe if we are really concerned, we could hold donated funds in an escrow account until the time to purchase this new server, so there would be no possible other uses for money that we want used to buy a new server.
