A couple of years ago, the ACF ran a highly successful Olympiad Appeal. I think it must have been the most successful ever. According to the Appeal website, the effort, in fact, raised a near unbelievable total of almost twenty grand!
But here we are again in yet another Olympiad year and so far the ACF hasn't asked for or announced anything about an appeal. I guess they must still have some pennies left from the last time.
