Qzzr content can be embedded on Wordpress.org blogs that you have installed and running on your own servers. Our script embed should work just fine for you as long as you're an 'Administrator' or an 'Editor' in Wordpress. The embed works by you pasting it in to a post with the "text" tab selected. Don't paste the script into the text editor when the "visual" tab is selected.
When you're all finished, it should look like this!

If you are familiar with HTML, you’ll notice that codes such as
embed, frame, <strong>iframe</strong>, form, input, object, textarea and others are missing from the above list. Those codes are not allowed on WordPress.com for security reasons.
