There is a problem while creating new courses. The news forum doesn't appear as usual if the latest news block is missing. You have to add the latest news block and than delete it again to make the news forum appear within your new created course. Refreshing doesn't help. It's quite annoying, because many people do not want to have there latest news block within their courses. There shouldn't be the need to add the latest news block just to make the news forum visible!
