Account creation failed: Error 700: please contact [email protected] for help if this continues.

Hi Debian-Team,

I tried to create an account on <https://wiki.debian.org/> because
I want to update the page
<https://wiki.debian.org/InstallingDebianOn/Thinkpad/T400/stretch>

But I get always the error:

    Account creation failed: Error 700: please contact
    [email protected] for help if this continues.

Can you solv this please

However, I have Stretch installed and:

1) Switch to External Screen

   BUT ONLY, IF the External Monitot is => 1280x800 pixel.
   It does definitively not work with Asus, HP and Samsung
   monitors with 1366x768 pixel. Maybe it is a Xorg problem

2) Modem

   Is working perfectly on /dev/ttyS0 togeter with an US Robotics
   i-Modem (external ISDN Modem)

3) Wireless/Wifi

   Even with Non-Free Firmware it is not working.

4) Keyboard's Hotkeys

   Working mostly, however:
   a) Fn+F2 (Lock)
      Has no function
   b) Fn+F3 (Battery symbol)
      Has no function
   c) Fn+F4 (moon symbol)
      Stretch fell asleep and can not more woke up.
   d) Fn+F8 (I do not know what this is)
      Has no function
   e) Fn+F12 (Suspend to Disk)
      Not tried it yet, because Hibernation and Suspend
      has the same effect as c)

Thanks in avance
