first... thanks for all the replies so far.... second... the website im referring to is similar to this one: http://www.flopturnriver.com/
I recently contacted Google and received a reply clarifying a similiar issue. You should get your own reply and now rely on what I say but: Your forum most likely is fine. Articles or conversation about gambling is fine. Links like you have leading to gambling sites is a big NO NO.
I think what he'll run into trouble with, the gambling links aside, is that the whole site is based entirely on gambling, which may be a major problem. But yes, do check with Googs for the definitive answer.
