I’ve written a plugin that does almost all of what you have here. The one thing it doesn’t do at the moment is change the page ‘furniture’. It does however use a good database structure, offer side-by-side translating and summaries and outputs semantic markup. It offers both your “Lazy” and “Full” translating. I’ve made the user-interface pretty straightforward too, I think (I hope). I’d be really interested in any feedback you could give, seeing as this is kind of the post everybody points to when they talk about a multi-lingual WordPress. I have a demo site up and running at:

If you’re interested, email me and I’ll set you up an account so you can see how it goes…

I run a site (WP based) which is going multilingual. After some research, I didn’t found any plugin which satisfied my requirements, so I thought I should swap the CMS.

I’ve been playing with Drupal (and its module “i18n”) and Joomla/Mambo (and its “Mambelfish” add-on). Although both systems are really powerful –much more than WP–, I feel much more comfortable using the WP admin interface.

Plus, none of the aforementioned add-ons works the way I like. So, now I’m taking the route of developing a new WP plugin.

Development has already started and at the moment I have a first (incomplete) version running at my development site.

Please feel free to contact me for more info (I’ll be watching this posts’ comments, too).
