As I promised today, here are two links concerning the translation of "Harry Potter" books into German.
This is where you can see all the threads (groups of topics) of the forum (the language of communication is German):
Harry-auf-Deutsch-Forum: Willkommen im Forum
And this is where you can announce your willingness to translate one (or two, three) pages of the new "Harry Potter and the Half-Blood Prince". Remember that you are expected to buy the English version yourself, and you ought to be able to have it in your possession by Saturday afternoon at the latest - maybe you can buy it at one of the Amberg bookshops on Saturday morning, or have it delivered to your doorstep via Amazon or one of the other online bookshops:
Anmeldung zur Blitz-Übersetzung
Before you can enter any contributions to the forum, you must go through a (short) registration process. If there are any questions about this, don't hesitate to ask.
P.S.: The above-mentioned forum is *terribly* slow at times, so don't be frustrated if it takes a while. But once you're registered as a translator, you'll get the address of a temporary forum which was specially opened only for the "Blitzübersetzung", and that's pretty fast. Very fast, in fact.
