I'm the creator of the Low Saxon language file for Opera.
That's enough for a start ;)
Added by someone on proxycache.rima-tde.net: this is posible?
Hey 22.214.171.124.proxycache.rima-tde.net, are you talking about writing on my page? He, he, not any longer...
If you are talking about creating a custom translation - quite simple. Take the english.lng and translate to your heart's content. When you're done, you may put your translation on Opera's languages list.
