Jon, we could have an open forum for the SIG. However, there would be no way to accept new members in a segmented way. You either accept everyone in an open registration or you moderate the way we're currently doing it.
The SIG forum has always been open -- once you're a member of ZHPMafia.com.
So, everything goes back to the beginning: do we open registration to everyone, including many of the asshats who participate in other forums we've left, or do we keep things the way we are and make people jump through an easy hoop?
We're not opening registration to the world.
