1. (previously (3) ) I would go with SIL's expertise with the
languages of New Guinea. It looks like the Solomonic solution for our
needs.
2. I agree with Michael that it's hard to find such areal experts,
that we are need for Southeast Asian languages, meaning that I would
go with asking André Müller to join us.
If nobody objects two proposals above, I would conclude them on
February 18th as our decision.
3. (previously (1) ) We still need an areal expert and hopefully
Wikimedian and hopefully a native person for Central and South
American languages. If we have no better idea till February 18th, I
would publish our request on wikimedia-l.
