As a starting point for discussions we have put together a set of rules derived from the HPF and MPI Forums. Everything is public and open. Most of the technical details hammered out in subgroups, which makes the base proposals. The main group discuss these proposals and votes on adopting them. Technical discussions for the most part done on email lists.
Subgroup bring their own proposal as handouts.
Unified draft put together from these. For running discussions, use loosely-enforced Robert's Rules of Order. Basically, we won't stand on formalities unless the discussion is becoming unruly. Moving and voting on amendments before the main proposal. Basically, this will keep the discussions focussed.
