You can create up to 10 static pages and they're automatically added to the blog's sidebar. Blogger uses the same editor for editing posts and pages, but pages have a different URL format and they're displayed in a separate list.
I tried to create a static page for this blog, but it uses a custom template and I couldn't find the "Edit Pages" section. Even when I manually entered the URL: http://draft.blogger.com/pages.g?blogID=<BLOG_ID> and tried to create a page, Blogger returned an error message and couldn't create the page.
