i suggest you have a look at DEUTSCHE WELLE - see link below . if you have the interest and the time , you should be able to find just about anything about the german language there .
you can take a free language course , ask questions , you name it , it's pretty well all there .
you'll probably need a bit of time to familiarize yourself with it , but it can give you a great deal of information .
you can switch back and forth between german and 29 other languages .
note the box on upper right where you select the language .
have fun !
