Bethesda support just the Englisch Language in the officially Forums. But is it allowed to post German Texts? Or is there a officially german Forum?

Only texts written in English are allowed on this forum

where is it written ? In the Rules? can you show me the part?

Certainly, friend.

From the http://www.gamesas.com/topic/724862-forum-rules-and-general-information/ thread

For all other information about this forum you can have a look at the http://www.gamesas.com/topic/662787-important-forum-information/ thread.

If you want to post texts in German I think your best option would be to search the internet for either a German Elder Scrolls fan forum or just a German gaming forum in general.

Thats not cool. Why is there no German Forum? WIthout the Permission to post german Texts this forum has no Permission to exist on my site...

I don't know if Bethesda hosts any non-english forums for their games. You could try messaging a moderator or an admin and ask if they can explain. I don't know much more than what is stated in the rules.
