Brian,
OCF does a world of good for those who are touched by this disease. Clearly, there are other expenses than just for the board, but lets start there, how much does it cost per year.... ? Perhaps it is more attrctive fot the "consumer" to think that: I made the board possible for xyz months/years?
Also, considering the consequences why not bring this to the attention of all registered users.... perhaps at the login?

Just some thoughts.
