Found a superb blogging tool recently called Post2Blog. It’s freeware and can be downloaded from: http://bytescout.com
After installation you configure it with your blog site’s details, login information, etc. Once you’re up and running all you need to do is create a new post and click the "Publish" button. Apparently it also provides Microsoft Office integration, although I haven’t tried that out yet. You can also manage all of you blog posts - edit, delete, move up/down, etc.
This is the kind of software that gives freeware a good name!
