I don't think he's counting on that type of sponcership anymore, his site will pay for any lost income and more (hopefully). Sponcers will still do the pipes radio though and Photoman is right, wouldn't make sense to be charged to list pipes when you could do that free here.
Personally I would prefer to keep tobacco trades on these forums since we are mainly looking to trade one for another instead of for money. It might even make sense to keep pipe for tobacco trades on our website too, since they are not being sold for money either. If we get forced into selling them for money, I will probabley both use this an a community site which allows us to barter again.
