I am wondering if anyone has had any experience doing website marketing through Internet Brands, Inc (www.internetbrands.com) They own a massive network of auto, home, travel, etc forums. And get several hundred million uniques per month.



I've seen many of their forums, and looked at some of the advertisers on the site, then did a Y! SiteExplorer search on them, and they have hundreds of thousands of backlinks generated from this and rank extremely well.



Any experiences with them? I want to contact them, if anyones used them, what were there rates like?
