How to let multiple people post on your blog

Step 1: Read the title
Step 2: Go to your "Dashboard" and select "Settings" on the blog that you'd like to have multiple authors on.
The picture uploader thing isn't working right now, so I can't post a picture of it.
Step 3: After you click "Settings", click "Permissions" (which is on the little bar).
Step 4: Under the heading "Blog Authors", click "Add Authors".
Step 5: Enter the e-mail addresses of the people you'd like to invite to make posts on your blog.

That's it!
