Lets go back in history:
We had over 10 NON military forums about year and half ago. They were shutdown due to repeated flames, political discussions and some other nonsense. We were deleting 50-100+ posts a day because they were either one liners or were flames. Other websites would have accepted those as "activity" and "content" but not here. So, at the end I decided to move all politics on different site (globaltalknetworks.com).
DefenceTalk would be A LOT busier today if we had those political forums but we rather go for the kill, quality rather than quantity of posts generated plus the true defence/military focus.
Thanks for the idea though.
