Made some updates today, I implemented some of the changes I proposed (not all of them) and made the copyright notice into "Uitgegeven onder de [GPL]" (may not sound as ominous as Gaelic, but I think it's okay). For "inbox" I just took "postbus" (a snail-mailbox), a technological intermediary between the parchment on the icon and the electronic mailbox. (Also, I've never worked at a normal office, so can't compare with that...) Multiplayer will stay as is, I'm (almost) at peace with that. I adapted the glossary as well.
GunChleoc: when exactly is translation freeze, can I send in stuff on Monday evening?
