There aren't any specific policies as of yet. Since the site is non-profit and donations so far cover most of my bills, I've been hesitant to start anything. But in the near future I hope to make a concerted effort at getting a full website up and running and when that happens I'll re-evaluate what the costs become and how to go about financing it. Until that happens, I've been fairly lenient with allowing posts in the pub from manufacturers and venders but would prefer that posts concerning items/products for sale go in the classifieds. If you have any questions, just lemme know.
Thanks,
