OpenOffice.org 3 supports 76 languages UI.
I predicted it when I was in Berlin :)
At the same time I predicted OpenOffice.org 4 supports 100 languages :)
This means OpenOffice.org Community has to add 2 (76 -> 100) languages a month from Oct. 2008 to Oct.2009 if we would like to see OpenOffice.org 4 supporting 100 languages before OOoCon 2009 :)
If your languages are not supported yet, subscribe dev@l10n.openoffice.org and start working on your OpenOffice.org localization.
And come to NLC!
NB: I don't know if OpenOffice.org 4 is released next year :)
