Memrise is a wiki, and we have got bunch of people who are helping to make the German content truly awesome. But there is still more work to be done. So please let us know what improvements would be most useful to you, and also if you would be able to help in any way.
Firstly, we have been developing some "conventions" for how German content should best be added to Memrise. Please take a look at these here(http://www.memrise.com/faq/german/) and add a comment to this thread with any ideas that you have for how these could be changed or improved.
We have then got a target of getting 5,000 words into the database, checked for accuracy and with audio added, by Christmas. This is a tough target, but with your help, we can get there!
