Sometimes you might publish a piece of content to a wrong section. It's easy to switch to another one.
Go to the 'Sections' tab and click the name of the section where the content is stored at the moment.
Hide posts from the stream on the right.
Go back to the 'Sections' tab and go to the section you'd like to move the content.
Click 'Hidden articles' on the top left.
5. Select section from drop down (the section from step 1 above).
6. Move content to the stream on the right.
That's all :)
