Hi Tony,
I have used it on a site that is not online any more (has been updated without the blog). But here you can see an example:
http://www.coffeecuphelp.com/flash-web-blogger.php
In order to edit the blog you will have to have the programme installed, but there is a shortcut: If you are on a different computer and want to update the blog, all you need is FTP connection to your server. Then you download the .txt file of the blogger and edit that, upload it again.
It is not possible to have someone else submitting comments to your blog, unless you give them access to the server.
But as Tom says, download it and play with it.
