I would also be interested in a language drop down in Spanish and Portuguese and probably could help with the translation if needed

There are some plugins that exist to mimic this functionality, but no, nothing exactly like what you describe yet.

The problem is translating post content, like categories, post titles, and body copy. There would need to be multiple versions of each item with the same slug, which isn’t currently possible with WordPress at the core.

Oh, forgot to add…the permalinks don’t work in the translated versions either – i.e. on my test site http://www.lleidaonline.net/blog works in Catalan but http://www.lleidaonline.net/en/blog returns a page not found error (badly translated except (so far) in the English which I’ve corrected (a nice feature of TransPosh).

Don’t forget to click on the US English (I’m also trying to find/write a British English .mo file so I can put a British flag instead of American, since I’m in Europe (and English!).

The main reason I want to do this at all is to cater for the two local languages, Catalan and Spanish, but have English available too. I also found a neat plugin for setting a different back end language but only managed to get that to work using the Codestyling Localization plugin which I couldn’t get to work completely as I wanted either).

Just thought I’d add that in the hope it’ll help others – here’s the Transposh link FYI, which is not usually mentioned but simpler than the main ones.

No, you only need one installation of WPMU/BuddyPress to have a multi-language website.

When you install additional PO’s and MO’s in your wp-includes\languages folder, magically in your Site Admin and Blog Admin settings will be language selection options, to determine the default language of both the site and the blog. The mu_locale function will take control of it and over-ride the WPLANG settings as necessary.

There is no user language settings as of yet, but I’m working on an implementation of qTranslate to allow for this. This won’t work until BuddyPress 1.0.1 as there’s a few specific things that need to be altered for everything to work in the order they need to.

@John James Jacoby – is it ready what you described here 3 months ago?

I am searching for solution to make buddypress multilingual, but only in interface: theme and admin area should has multi language texts. ost dont have to be translated.

Just something like is at wordpress.com: user register and choose language. Then he see all interface in local language, write in any language he want.
