How to Save and Publish
Publishing is the ultimate form of making your completed work public. As soon as the publish the world will see the changes you made to your page/subsite.
Step 1: Save & Close
The Save & Close function does exactly what it describes. Once you have finished editing, click on it to save your work and close editing mode.
Step 2: Check In
Checking in a page after you have saved your work will allow others (who have access) to edit the page before the world sees it. For example, if Mike has just finished editing a page, he can now Check In the page so that his boss Mary can see and edit the page before deciding to publish it.
Step 3: Publish
Once you have verified that you want the world to see your work, select “Publish” to unleash its wrath.
Tip: directly Selecting the Publish button will perform the following three steps – Save & Close, Check In, and Publish
