A quick overview of the main changes:
The governance structure is more specialized. It separates officers responsible for administration of the constituency from officers responsible for policy development and representation. An Executive Committee, composed of 5 regional representatives, a Chair, and a nonvoting Secretary-Treasurer, manages the NCUC website, email lists, elections, and membership processing. Most of the responsibility for day-to-day administration is clearly fixed on the Chair; thus, whoever is elected to that position must take significant responsibility.
A Policy Committee, co-chaired by the two GNSO Council representatives, represents us on the GNSO Council and its task forces and work groups, develops policy positions, and handles membership policy development initiatives. GNSO Council reps would be elected separately from the regional representatives.
In the old structure, an "Administrative Committee" was responsible for both administrative and policy functions. Worse, no one person on the Adcom was given responsibilty for anything in particular. The main result was that neither administrative nor policy development functions were performed adequately, and there was no clear mechanism for getting the NCUC's work done.
Membership eligibility: Membership eligibility is substantially the same as before, with the exception that independent chapters of national or international organizations can now join as separate members. The proposal decided that noncommercial organizations with ccTLD domain names would continue to be eligible for NCUC membership.
Mailing lists: By rapid and unanimous consent, the committee decided that only NCUC members would be able to post on the discuss list. There will continue to be a separate "announce" list. There will also be a separate list for the Executive Committee, which will be restricted to EC officers but publicly archived.
