1.) Posts have to be four lines or longer when a debate is taking place.
2.) Watch the spelling.
3.) A measure of logical consistency to every argument.
4.) Emotional posters, such as religious zealots, left-wing nutters - out.
Other steps should involve:
-Merging Symposium with new forum.
-Creating incentive for posting quality topics, including rep and awards.
-Creating propaganda campaign in CC to give regular members a chance to prove themselves in the new forum.
-Create a new civitate process that includes this forum as a major stepping stone for civitatehood. Those who succeed in writing quality posts, will be invited to become civitates. Those that fail to do so, will have their right to post in the forum revoked. Let's say it's an initiation test for right of passage.
