"HN Board"?

I have a question. I saw a reference on another site to the "HN Board"? Does anyone know what that is? I'm not shilling for a competing site, I'm just trying to keep track of all the available resources.

Thanks!

Maybe PM the original poster. I'm not familiar with the initials, but he might have meant HornDogs and hit HN instead of HD? (because "Horn" has an "n" in it , it seems a likely error).
