For those of us who use windows based computers, Windows Live Writer is a tool that allows us to create blog posts offline and publish them when we're ready.  You can download WLW from the WIndows Live download area.

If you haven't already set up your Blog, you can find instructions here.

The first time that you run WLW after installation, you will be prompted to set up your blog account:

Choose 'Another weblog service' and click Next

Put in  http://my.lotussevenclub.com as the weblog homepage and then put in your www.lotussevenclub.com username and password and click Next

using the link in the MyWords box.  On that page, in the Metaweblog options section, you will find the address that WLW needs to be able to post to your blog

Once WLW has finished all that it needs to do, you will be presented with a screen something like this:
