Put a description of your blog post here, of up to 200 characters, in a single paragraph. It will show in the blog frontpage listing, in a smaller font, under the title.
Make your full writeup here. Use as many paras as you like.
If you include images in your post, then the topmost image with a non-blank alt tag will be used in any blog catalog theme which places images alongside content links.
Note: if you are using a subsection blog you will probably want to save the file as 'blog/pagename'
