Just for the sake of clarifying, my comment about pitching a tent in someone else's yard was an attempt to address the way I interpret the idea of your new forum and not about you personally.
My impression of your idea is that you are creating a Cellar-like forum within the cellar - it was a mild critique of what I perceived to be a missed opportunity to expand the scope of the Cellar (by bringing a new concept for a topic header such as Religion or Paranormal phenomenon or Health. I think that a new forum under one of those header, for example, would actually
generate new posts that might not otherwise have been.
It is my opinion that creating a topic header such as you propose merely spreads the exact same number of posts over a wider number of topic headers. In other words, I didn't sense that your proposed topic of "controversy" would really
add any new posts since most of the controversial issues tend to show up in one of the first three topic headers already (Home Base, Current Events or Politics).
I'm not trying discourage you from starting a forum - just suggesting that you consider defining it a little more uniquely. But, that's just my opinion and your's is just as valid. Peace
