Absolutely love the site, quick idea popped into head thought I'd spill 2 cents. Currently we have a board with the description "Talk About Clever Stuff" entitled "Science."
Thought it might work to re-name it to something that would encompass a greater scope of topics such as: philosophy, politics, etc. This would allow for a potentially more active board, and allow a separation between more serious topics and the General Discussion board.
While I'm not sure the name "Science" was to exclude other topics, the name can easily imply it or give off the impression.
