My suggestion is that we have a forum where topics can only be posted by moderators. A topic for debate will begin only after the following conditions have been met:
- someone has been identified as the proponent to the point to be debated
- someone has been identified and has agreed to be the opponent of the point to be debated
- the proponent and the opponent have agreed on the wording of the point to be debated (perhaps there should be a discussion forum for this purpose)
