How to do offline Blogging?

There are many ways to do offline blogging ,

Few of the are below…
Windows Live Writer:
When you use a desktop software, such as Microsoft Word, to write an entry and then paste it to iMechanica, the format often looks bad. Instead, you can use Windows Live Writer to write blog post offline. Installation takes about 5 minutes. The Live Writer has a remarkably clean interface, and is very easy to use.
You can set up a list of weblog sites to contribute to. You can write, edit and store an entry offline. Whenever you feel ready, a click on the button "publish" will post the entry to your chosen weblog. All the format will look right.
You can even insert an image.
To test the Writer further...
• I can also do inline spell check by clicking "abc" in the toolbar.
• I can add a link behind a phrase.
• I can only post blog entries, but not forum topics.
• When I change the title of a post, the Writer treats the post as a new post.
• I cannot upload an attachment within the Writer. Of course, I can always click "edit" of my post, and add attachment.
