WP-Multilang

[soft79]

Check out https://github.com/VaLeXaR/wp-multilang .

It is another very well written multilang plugin that uses [:en]language tags. It is written from scratch but can be migrated from q-X with little efford. I remember the author mentioning he was looking for members to maintain/develop the plugin.

In my opinion WP-Multilang has a cleaner code base than q-X.
