You can make a web page on your blog if you like. It’s called a “static” web page. Go to the Dashboard, click Write and then Write Page. Enter your information just like you would if you were entering a blog post.
You may want to make this “static” web page (or a different one) your “Home” page–where people go when they come to your blog. That’s what we’ve done with this blog. The advantage of this is that your web page will basically stay the same after you update it (not counting the changes you make), whereas with a blog your most recently updated post is the very first post that people will see on your blog when they come to it.
To make your static web page your home page go to the Dashboard, then “Settings” and then “Reading”. Under “Front Page displays” choose the “A static page” and pick the static page you want to use. Save the changes. Now when people go to your blog they’ll go to the static page you just designated. Even if you add new “posts” to your blog, people will initially come to your (static) home web page.
