WordFez is a plugin for bilingual (French-English) posts. It is seamlessly integrated into WordPress using a TinyMCE plugin.
It will add 2 extra buttons in the WYSIWYG interface for French and English language. Each button inserts 2 anchors to surround each language. The anchors are labeled by small flags. 
The usage is very straight-forward. The plugin comes with a widget to allow each reader to conveniently and instantly switch between the languages.
