Will this motion damage the rating system?
A better question - Did this practice damage the rating system? (as it was practiced for several years) IMHO - no
vs Did it contribute to the Canadian chess and to the CFC? IMHO - yes.
As a parent I had some benefits from this practice: a track of son's results with regular and prompt updates. Personally I would not care the system used - CFC, CMA or a local rating system.
As Fred McKim wrote once, to process juniors' ratings the CFC looses monies through Director's time. (imho, it should not be a case, on other hand for a non-profit organization it might be a plus to support juniors.) Indirectly the website should generate monies when players/parents check ratings. Thus the CFC should be financially neutral on this matter in a semi-ideal world.
I'll support this motion. While I'm not sure that about the amendment. Why is it December 1, 2011? Not May, 1 or July 1 (Canada Day)
