The Thai community of Firefox localizers is very busy these days.
Last week they held a localization party called “House 2.0” where they worked to finalize most of the localization needed for the upcoming Thai Firefox release. This is very similar to the German Mozilla community who recently also held a “Hack’n'Cook” event. I am looking forward to the Thai locale release.
UPDATE: Molecularck has an overview of the House 2.0 Firefox Thai l10n sprint and blognone has a nice overview in Thai Firefox 3 Thai localization sprint วันที่ 2 และ 3
