I'd like to inform you that code according to the specifications at
http://meta.wikimedia.org/wiki/Multilingual_MediaWiki
is now under development by Dominic Arkwright, an experienced PHP/MySQL
developer who is new to MediaWiki. Dominic may pop up on IRC or on this
mailing list to ask questions. If you haven't done so, I invite you
again to review the specifications above and make comments on the talk page.
Regards,
Erik
