Re: How do plugins like q translate, BP Translate and BP Multilingual work?
BTW, I found all this helpful info:
Manage multilingual posts in one post per language (for example Gengo and WPML). Translations are then linked together, indicating that one page is the translation of another.
Store all languages alternatives for each post in the same post (for example qTranslate).
Manage translations on the generated page instead of using a post context (for example Transposh and Global Translator)
Plugins that direct you to external translation services (for example Google AJAX Translation)
Plugins that link together separate WordPress installations for each language by pinging back and forth.
I’ll try a few more options but sure would appreciate some suggestions.
