The main purpose of the plugin: translation of articles and posts on your site by ajax. This is necessary for example when the site is mainly intended for an audience speaking the same language, but still some of the articles should be translated into other languages, for example you are a developer, blogging, but some instructions and descriptions of some product you need to write in several languages.
Plugin doesn work with translation services! The principle of the creation of the post of the translation, where the translation writes by hands. Services is good, but the translation of large text by them is funny.
The advantage of this plugin is ease and simplicity. You will not need to install big and heavy plugins for only a few articles. And flexibility - there is no binding compulsory languages - each article or page is unique.
