I help run a site with four languages. We upgraded last year (we're on 3.5.1) and though previously our default language was en_us, the new site was accidentally set up with en.
We'd like to switch back to en_us, but we have a lot of multi-language content (front page, site pages, etc.) using non-html tags, i.e. "{mlang en}content here {mlang}."
After installing en_us, is there a simple way to tell the system to display en content for any en_us users? (We can remove en from the language selection - we don't need both - and many users have en set in their profile.) While we could edit all the content to replace mlang en with mlang en_us, that's tedious and prone to error or skipping a message or two.
Also... same thing but replacing pt with pt_br. We've found that 90% of our Portuguese speaking users are from Brasil. Again we don't plan on supporting both pt and pt_br content, at least not for a long time.
Thanks for any suggestions. I can change source if needed to save hours of editing and proof-reading.
