For those of you with Windows, here's an option for you. I have been using this for the blog on my personal website, that I post to occasionally, and the great thing about it, is you can compose your posts off-line. The down-side is that unless you have an FTP site for your images, photos etc. it will not upload images to blogger. However, after publishing, you can always access the post on blogger and add images from there.

This is my first post using it, so I'm still experimenting. I'm sure I will also use blogger to compose, but until they get the Auto-Save in gear, think I will continue to use this.
