I know this is your board/site etc but surely your posts need to be above reproach and I don't think rule #5 on the 'for sale' board you posted is very good. 'crapping' is an obscene word and should not be posted on a public forum. (In my opinion)
(5) No thread crapping. If you think a price is too high then don't buy the item. Low ball offers should be made by pm and suggestions on a lower price can be pm'd also. HUKD members are pretty savvy and know to check out prices elsewhere (i.e. eBay) before buying.
