you are always going to have people that are passionate about something and you will always get little flamewars happening - we have 2 options that you might be familiar with:

Benevolent Dictator or Free Society.

• the Benevolent Dictator will review topics and remove the ones that don't or won't sit well with how they believe the forum should run.
• In the Free Society we love freedom that allows people to voice (dissenting) opinions and accept the responsibility that goes with it. This would create a self policing forum.

I prefer the free society but believe we need more self policing tools in order to grow as a community as our ranks continue to swell. There are a variety of ways to enable self policing and we can look at a number of models that currently exist with minimal supervision - a la craigslist.
