How can I make my Tumblr blog public?

To change your blog to a public blog go here: http://www.tumblr.com/blog/nameOfBlog/settings

• Scroll to Password section (near the bottom)
• Uncheck the box labeled: "Password protect this blog"
• Click "Save"

Notes:

• I wasn't able to find this setting on my existing Tumblr blogs
• It may be that once you post something public you can't turn it back into private (unverified)
