How do you make text vertical in Word 2010?

I don't know of a setting for that specifically but you can make a text box, type in the text box and then re-size the box so it is narrow enough to only allow for one letter per line. It will automatically push letters to the next line as the box narrows.

• Enter your Word art as usual
• Then click on the word art box you just made
• Make sure you click on 'Format' on the top of Publisher
• Third option across the top says 'vertical text'
• Click and your text is vertical ;)
