Hoi,
As a result of our exploring opportunities for Ultimate Wiktionary, I was pointed to LISA the Localisation Industry Standards Association. I downloaded some information and was asked afterwards for some information. This in turn led to the question if I was willing to write an article about Wikimedia and localisation. So I did. It can be found here: http://www.lisa.org/globalizationinsider/
Thanks, GerardM
