EPiServer Community has a globalization system which uses the database. The keys and values are configured under System Settings -> Globalization and accessed in code with the EPiServer.Common.Globalization.GlobalizationHandler class. This solution is great as it allows the editors/moderators to change globalized strings on their own. It's not as popular among developers though as it's requires us to leave Visual Studio :) One solution to speed up entering the globalized strings is to first enter them into an excel sheet and then paste them into the database table. This assuming that it's not a live site of course.

Thanks Joel! That is exactly what I'm looking for. I'll be checking it out right away - and get back to you with more questions along the way ;)

The GlobalizationHandler class solved my issue. I do see a lot of potential for making the admin interface better, I'll definetly be contacted by users on how they can find a certain string. However, making an extesion to the admin interface could be done relatively easy I think,
