If it's a site dedicated to open relationships, then there's unlikely to be much about poly relationships. Open /= poly. There are many poly folk who don't have open relationships (though there are many who do).
Also, you've one post and it's promoting a non-poly web site. I'm going to remove the post from view until I can confirm that you're here to participate and not here to market the site.
When speaking of various forms of non-monogamy...it ain't poly if you're just fucking around.
While polyamory, open relationships, and swinging are all distinctly different approaches to non-monogamy, they are not mutually exlusive. Folks can, and some do, engage in more than one of them at a time--and it's all good.
