Well, having put more thought into it, I think the world needs more Pagan forums. I mean, it's not like every cafe druid and cherohonkey with a copy of Mists of Avalon hasn't started one, or that they ALL turn out the same way.
Prediction: No matter how good the intent of the 3 people involved, no matter what examples they have to warn them, within months they'll be strongarming people with the mod button.
Why? Because Paganism is - and always has been - about control. Gardiner and his friends, in Wicca's case, wrote that RIGHT INTO THE RELIGION...So that they could use it to control the rubes that followed them.
TGRR's Dictum: A Pagan board will go mod-happy just as soon as they have a base of believers that have to be "protected" from any test of their ideas from an outside person or group.
