Hi We've received a couple of request for a tool or script to change the master language for a site. Such a tool is to be developed but for now, you can manually change the language branch table to switch languages. Let's say you got a site running with english as the master language, but the content is written in swedish. What you need to do is swap the LanguageIDs for english and swedish in the table tblLanguageBranch. To do this you'll need to temporarily re-name either of the two LanguageIDs to an Id which is not in the table due to restrictions in the table.
