how would I make the site support sychro-edit?
A doctor told me that mediawiki do not support sychro-edit e.g on this platform-http://www.joyouswriting.com/index.php?title=%E9%A6%96%E9%A1%B5, students would not edit their essay at the same time. Is it true that mediawiki do not support sychro-edit?
