Moderators
Moderators are a group of volunteers who help maintain order on the forums. They help enforce the rules and make sure the forums are a fun place to be. Please remember that moderators are humans and not robots and if they make a decision that you disagree with you cannot argue with them in public. Instead contact them privately to resolve the matter, or contact the Administrator.
It's the same reason you don't argue with a teacher, coach, parent, work supervisor, etc in public. It generally leads to a larger problem. If you haven't noticed, arguing with mods in a thread generally leads to more warnings and bannings in some cases. We have to maintain some semblance of order on the forums. Taking a problem to a PM keeps anyone else looking to cause a problem due to some issue out of the picture and keeps the situation from snowballing into multi-warnings/bans, as we've seen several times in this forum. I've been wrong at times and have gone into the threads and apologized in a post for all to read. Get back here an read!!!!!
Well, as long as it's st least semi-civil there shouldn't be a problem. But if someone just goes off cursing, bashing and throwing accusations in a PM, then I can see that being a problem. Not that I've known you to do that sort of thing. I've found a trump to your loophole.
