Excellent set of questions
Steve - that's a very good question.
My experience is limited to our traditional Commonwealth regions. Having had the privilege of working in these different regions - I can attest that the differences are tangible. The Pacific way of doing things is very different from Asia. Having grown up in Africa, I can attest that African culture is different from the Caribbean. This cultural diversity is a unique asset of the WikiEducator community and differentiates us from other international projects.
Personally I would like to see the WikiEducator project preserve and promote the regional diversity we have by providing an equal voice to all our regional communities. The advantage of involving another International agency like UNESCO is that we could incorporate the regions we are unable to cover under the Commonwealth. For example the CIS states of the Russian Federation, the Middle East, South America etc.
I don't in any way presume to know how best to incorporate these ideals in a Board for WikiEducator - but I do know that we will be richer for the experience.
Hope this helps ...
Another way to tackle the issue of regional representation could be to have an regionally elected 'Executive Committee' which could have a much larger representation from the wikied community - say between 4-5 from each zone. The Advisory Board would be directly elected too. The executive with the regional representation should have the role of coordinating activities zone-wise and reporting and coordinating with the Advisory board. This would take care of region-specific issues. What do u think?
I am not comfortable with incorporating regional and gender limitations when seats come up for election each year. This will mean that the gender composition of the first board will decide the gender bias for all future positions!!! I would also agree with additional slots for gender and regional adjustments - of course we set an upper limit.
Also we need to lay out what kind of subcommittees we need - some that I can think of are the finance/funding committee, the technical committee, the social out-reach committee etc. We need collective decision in all our actions/activities.
