A year or so ago Blogger followed WordPress in allowing you to create static pages – called Pages – to complement the periodic, chronologically listed series of postings typical of blog platforms. You can use these Pages for more or less permanent material such as an Introduction, Contact information, Guidelines. You can also use them for more dynamic ends, such as feeds from other websites.
1) Go to Design > Posting > Edit Pages
2) click: New Page
The new Page has a url that you can then use to link to from anywhere else.
