The main Problem is,
that Germany was sliced into 2 Parts in History...
BRD German Republic, and DDR German Democratic Republic till 1989.
In school BRD had to lern german and englisch/french language, in DDR thy had to lern German and Russian, but not englisch nor french.
This people (nearly the half of german people) lerned english a little bit ... but after 1989 so they are not very comfortable with it... and often feel bad if they have to speak, or write english.
That there is ainternational german subcategory is a very good thing, and make it easy to post for such people related to DDR.
But there is a thing to optimize... every thing is mashed up there...
Questions about code are mixed with things have made with arduino, questions about hardware... and so on...
This is colorful

but if you want something to know, search something it's a little bit messy and mixed.
The englisch part of the forum... the main thing, is proofing that this is the better way.
And I think so too.
So...
i know some International Communities... that changed active boardusers to Area-Administrators/Moderators... the best of them if they want to...(active, most knowledge) are cleaning and administer/moderate the Subccategories of their language-buddies areas...
Sub-Bosses in some way...
I think it is easy to do that thing by a Member- Request (Public),
Do you want to be a Board-Administrator/Moderator of your Country?
Has the international Boards to be subdevided into more special subcategories?
* YES
* NO
* I think it is unneccesarry to subdivide the international board
* I think the subdivision of international Categories is neccessary
Ok, it doesn't have to be... but it is a better chance to improve postings, research, searching, overlook....
I don't know the Yabb Software... but i am Administrator of 2 Boards on phpBB. On phpBB subdividing is a thing of about 30minutes to devide all international Categories into about 5 Subcategories.
The main working task is to move the old posts into the right new subcategories.... but this could be easily done to open an "Old Posts Archive" ... and starting fresh with no posts on new subcategories.
