why don't you accept the invitation to moderate it? You seem like you can remain neutral to facilitate. And my "vote" says DO IT LIVE; IN STUDIO somewhere... or at a public event. NOT skype if possible. There has to be an upcoming LP state convention which would be convenient for the 3 of you to make. Yes?
Not only "should" it happen... The future of the LP is dependent on the outcome. ....especially since the Minarchos have been so asleep at the wheel since y2k.
I amend this suggestion to say: If Berwick is the moderator, Skype is fine.
