Have you noticed the new subject headings at the top of the page under the blog's name banner? Blogger now allows you to make separate tabs or pages. I've taken advantage of this and posted the topics that I've had the most discussions about.
Want to add some to your blog? Go to the "Posting" section of your blog, or you can click on "Edit Posts" or "New Posts". Just under the main menu tabs there are three sections: New Post, Edit Posts, Edit Pages. Click on "Edit Pages". Click "New Page" and start typing.
