I currently use the excellent qTranslate plugin for offering a Chinese version of a client's microsite.
However, I'm currently merging their microsites (each with a separate WP installation) into their main WP site. But they only want to offer multilingual facilities within the new "microsite" (effectively a specific WP page and all its descendants).
I'm in the process of researching this, but I thought I'd ask if anyone can recommend a multilingual plugin that has this feature - to selectively enable the plugin's functionality only on certain pages / posts?
