I have some KB articles which contain example URLs. These are being automatically hyperlinked when I save the article. I have tried countering this by wrapping the content in 'pre' tags, which successfully disables the auto hyperlinking. However, I have tried placing a class on the 'pre' tag so that I can override the CSS styling it—this class is always removed.
Is there another way to stop the auto hyperlinking or is there a way to add classes using the source view and have them stick?
