Thanks for clarifying. If they want to have something like an "EDIG lovers" board, so be it. I hope that it would be clear that it is a censored board. I would not want to be part of that kind of board anyway.
However, I can virtually assure you that if they had to pay a buck or two a month for the privilege of a board they could censor at will, you'd get few if any takers. Most of the EDIGers are freebie grandfathered status. At least one criticises me on RB because I was "desperate" enough to pay for a membership.
If you do it without charging for it, I hope the ad revenue will support the cost.
