As a total outsider who has never been to Moldova, one more aspect has come to my mind while reading the above lines:
Does the fact that a small minority of people might prefer to use the Cyrillic script for private purposes justify the enormous effort of building an entire encyclopedia for them - while they know the Latin script?
My point is: if a society generelly uses one script (which seems to be so according to everything I have heard from our fellow Wikipedians who know the country as well as the language) it doesn't really matter if an individual likes another script better. They will have to adapt to the common standard if they want to read the paper, a current book, the phone book, the signs in public places, labels on products etc., make they annual tax declaration, do business, get a job, ride a train ... So are any severe reasons for Wikipedia to make an exception here?
In Moldova proper, virtually everyone knows how to read/write Latin script, because the government isn't allowed to use Cyrillic script (it's unconstitutional, since Latin is specified as offical script). The case is quite interesting - in rural areas, less people actually write in Cyrillic, because rural areas are much less Russified. In urban areas, those who previously wrote in Cyrillic have been accustomed so far to ubiquitous text in Latin. So, as I said before, I don't think this Cyrillic script Wikipedia serves any really practical purpose.
Having said that, there is still one open question: the issue of
Transnistria which does not make things easier and may not be forgotten, of course.
Yes, Cyrillic is official there. Remember, though, that Transnistria is basically the continuation of the Moldavian SSR (Soviet Moldova) - it has the same flag, it operates under a dictatorial structure, and it's maintained Moldovan-Cyrillic. There was media coverage some time ago that the Transnistrian government had closed down Moldovan-Latin schools, which were quite plentiful. Romanians/Moldovans in Transnistria are quite widely persecuted and basically unrepresented politically. Their "emotional" links to Moldova and to an extent Romania are therefore quite strong. I presume about half of those people would know and prefer the Latin alphabet, which leaves about 100,000 people that would actually write in Cyrillic and may have some trouble reading/writing Latin script.
