The dedicated advertiser forums we had were too hard to manage (along with all advertising in general) so everything has been consolidated to one advertisers forum. People probably don't realize all that goes on behind the scenes when you have 40 or so companies with banners and block ads. You can end up with 5-10 advertisers missing payments, lots of chasing up, disabling/re-enabling their forums and advertiser status, disabling/re-enabling their ads, obscure payment method requests, etc. I am now taking a more hands off approach to advertising by turning it over to a professional firm, this way I can focus more on the site itself. Since I am taking a hands off approach and reducing sponsor forums, the ads have become cheaper. I will contact the advertisers though, and encourage them to place company information and links in their signature.
