@dlowan,
Not unless they want it to be (and I don't think they would, I don't think they want a closed society so much as something closer to their previous culture, an open group lets them have that as new joins have to acclimate to their culture as they come in).
But for now please hold the questions about the coming philforum, I am going to build the software, I am not going to run the philosophy forum. I've asked the previous administrator jgweed if he will accept that role and any such decisions will be up to him.
If any of the previous philforum folk are interested in joining the mod team of the coming philforum group please use the contact us link at the bottom of the page.
