Seems like a pretty handy tool. I have been checking out offline blogging tools like Blogjet, Qumana and Blogdesk (which I have been using), because I desperately needed a spell checker! This looks the best of the lot so far and is free for the moment, and it is defintely the prettiest. Thanks for the heads up. :-)
Nice blog, btw. I heard about it from Tim and have been checking regularly since. Keep it up :-)
