Scott,
What would you charge to host another board here? At present, it's very small -- only 38 members (I thought more, at first). It might grow, but I think not.
One issue is that most of the members are wannabee writers, and are paranoid about search engines exposing their work and eliminating "First Serial Rights." I don't know what to do about that. The mailing list currently used, on Google Groups, only allows members to read posts as well as restricting posting to registered members.
I personally have neither the space, the expertise, nor the Web connection to host anything. The others are in pretty much the same boat, although something might be found.
This might not go anywhere. But I thought I would ask.
