@ejm, my experience has been the same as yours–and very different from @Arzny’s. We’ve sold 50+ horses through both Keeneland and Fasig, and like you, we’ve been able to correct typos and incorrect info, and provide updates before the deadline. But other than that: nothing. Not even changes that make perfect sense from a sales POV. This has been true when we were with both small and large consignors.
@Arzny, I’d be curious to know which sales are letting you (re)write your pages and which consignors have the clout to make that happen.
