DONE: Add a General forum

[Chealer]

Greetings,
The application suggests asking questions here, but there is no forum for questions.

It may be good to create a forum for questions, but I think there should first be a fallback forum for topics which have no appropriate forum. Or it should be possible to open a topic in no specific forum (in the root).

Not a bad idea. I've created one.

Thank you Jens
