When I called up your post, APUG attached a banner box listing APUG advertisers -- so I clicked on Calumet Carton Company. And was taken to Cox B/W photography. Cox's own link properly took me to Cox, so it appears that someone at APUG HQ has failed to properly input your web address in the hyperlink. FWIW, Christopher Walrath's link is dead. I didn't check any others, but I think the APUG advertiser banner needs looking at.
