Which word processors and websites support vertical writing of Chinese? I am aware of 好讀, which allows you to read Chinese novels displayed vertically. 


Is there a convenient (preferably free of charge) word processor if I wish to type a Chinese document vertically? 
When I browse a Chinese website, it there a way to convert the writing to the vertical direction?
