After recent ISO-639-1/2 changes (http://www.loc.gov/standards/iso639-2/php/code_list.php), 'mo' language code becomes deprecated, and Moldavian or Moldovan become alternate names for Romanian (ro).
Therefore, this code should be removed from Mediawiki files such as:
http://svn.wikimedia.org/viewvc/mediawiki/trunk/phase3/languages/Names.php?view=markup
This also affects Wikimedia resources such as mo.wikipedia.org, which uses a non-existing code and, IMHO, I think this has little sense to exist as official project in Wikimedia. Actually this has also received little activity for months.
In contrast to other languages such as Serbian, Romanian using Cyrillic script is not a contemplated option and only Latin script should prevail.
