Post it. Share your wealth of knowledge with the rest of the community. If certain info is traded privately, what becomes of the community that we have created? Airlines and hotels will certainly be able to infiltrate any private discussion group by swearing they are an honest Joe. Once that happens, the private groups will give up, realizing their efforts are futile. Besides, it's fun to brag to the whole mileage-addicted world about your saavy and intelligence.
