~~ on how your Board should be utilized?

I appreciate when someone posts their "deals"... I have picked up some GREAT chips at GREAT prices from a half dozen people ~~ RECENTLY ~~ because of posts and scans on this Board. Many were chips I wanted already and best of all -- I got them for prices much lower than I had hoped.

If there are guidelines or "breaches" of ettiquette committed by me or others, I would be grateful to know exactly what they are... out of respect for our hobby and host.
Thank you
