I am a little bit late to the party but it looks like REW has been struck with some sort of Google Penalty. A few people at REW noticed that site was not ranking for some terms that they did well on previously and even lost rankings on their own name. Currently their forum ranks first for the term Real Estate Webmasters but not the main page. Under it are a few blogs discussing the issue of REW losing rankings. Morgan wrote a blog post discussing it here. A couple of other bloggers wrote about it as well but they delve a bit deeper into the actual reason why the penalty occurred. Check out this blog and this blog.
Update: It appears that REW is back to their previous status (at least after a cursory review).
