As far as forums go, Subsim is about the best I have seen anywhere. Sometimes there is a tiff or two but not like some forums. It seems most know when to stop concerning flaming etc. with this forum. It makes is nice to be part.
Neal keeps a good reigh on it and Seth keeps an eyeball on it. This is what forums need. If the forum keepers says he will ban for XYZ and XYZ happen, then ban!!! If the forum keepers let some people slide, soon all will be sliding. Have rules, stick to them, enforce them as needed.
These flamers need to realize it is a privilege to be part of a forum....not a right! Forum owners can ban at will and for good!
