Thanks Aye--I'd just add that the rules regarding pedo accusations and directly dragging a poster's family into the debate still apply..even in the 'free' zones.
The rule about addressing the topic is, by far, the most ignored one here.
I find, reporting offending posts--and referencing 'flame, no topic' gets results. Not always..but Mods are human also.
There are some here whose only really purpose is to troll and derail threads--if you identify those folks and ignore them..you can improve your USMB experience. There are a few 'one trick' ponies here..if you like the trick, cool..if not...ignore is, once again, your friend.
