Currently our users have to create two communities if they want to manage a blog in two languages.
The only solution to avoid this situation is to set both languages into one post. For small posts this maybe works but bigger posts would become very confusing.
The same problem happens with wikis. The users have to create every page two times for two languages. Our HR sometimes need to provide information in more than two languages. The missing multilingual support makes this situation very complex.
Our users worked with Confluence in the past. Here it is easily possible to manage one wiki page in different languages.
The idea is to have a language switch wich makes it possible to change the language of the content within one wiki page / blog post. This would be easier and for example the table of content of a wiki would be leaner.
