Switching over to Blogger's new editor
The editor is where you compose and edit your posts. The "Read more" function is easily accessible in the new editor, but you may not have switched over yet. Let's do that now.
After logging into your Blogger account, you will be taken to your dashboard. Click on "Settings".
Scroll all the way down to the bottom of the next screen. This will be the screen for the "basic" tab. Under "global settings" you have the option to "select post editor". You want to click "updated editor" and then "save settings". This change will apply to any other blogs you have.
If you're using a heavily customized template then you may need to insert some code in order for this function to work properly. See this post at Blogger Buster for help on adding the read more function to customized templates. For example, in this tutorial I've manually inserted the Read more link at the top which is why it didn't disappear when you clicked through to read the entire thing. But I'm a mere humble guest blogger and don't have access (nor permission!) to go rummaging around Amanda's code to fix things.
UPDATE: Please see this post at Blogger Stop for solutions to three common errors you might get with the "Read more" function. The last two errors I've encountered while doing this tutorial!
P.S. In honor of this tutorial I inserted jump breaks all over the posts that appear on the front page of my personal blog. It was a lot of fun and I now feel very professional.
