Here is the setup. We open a new thread where only you, myself and any moderator can post. No one else can post. One person will start and the second person will respond. We can do 10 posts each. We open a second thread so anyone can comment on the ongoing debate. People can post to their heart's content on the second thread. At he end of the debate, we have a poll to see who won the debate.
Is it possible to set up a thread where only myself and DK, and the moderators can post? If not, we can have a posting on the debate thread asking people not to post on the thread but to post any comments on the second thread. If anyone does post on the first thread maybe one of the moderators can delete the post.
