Big Sorry. Whoever tried to register for the last two months and always failed - probably because of us.
Two months ago a filter against trash and spam domains was set up here, with almost 28,000 entries. Unfortunately, the filter was "too sharp" and contained a number of popular domains, including gmail.com, gmx.net, t-online.de and yahoo.com.
We overlooked this and have now corrected it.
To all concerned: You can register now. And sorry again.
