could not register in debian wiki

[Helmut Roewer <socialnetwork@helmut-roewer.net>]

Hi debian wiki administrator,

I would like to register myself in the debian wiki, because I also want
to help to improve it. My registration failed - and this was the error
massage:

Account creation failed: Error 920: please contact
debian-www@lists.debian.org for help if this continues.

Please help me to register!
This is my nickname: dunkelangst
and this was my e-mail adress: socialnetwork@helmut-roewer.net

Thank you very much!

Best regards from Switzerland
Helmut Roewer
