Sadly, I have attempted to use this plugin twice. Both times the plugin demands I sign up their site and nothing ever happens. The only thing the extension does is have a login button that redirects to the site if I am logged in or not. What a shame. Even if I am doing something wrong, it only allows me one option. To edit my work on their site. Which I wasn't really needing to do. So, 1 star.

In short, very good to use. If your grammar and punctuation is a bad as mine then this will be a added bonus to use to help correct spelling mistakes on your application forms and emails and social networking, etc.
