Security Note: You really ought to register a valid e-mail address. If Foswiki can't find a registered e-mail for you in the secret database, it will look in your user topic for a form field called Email. If this form field does not exist it will look for a line like this:
* Set Email = user@example.com
If your user topic is not protected from changes by other people, and you don't register an e-mail address using this form, then your user account could be hijacked by someone else.
If your old e-mail addresses are all invalid (you can't receive mail there any more) and you have forgotten your password, please contact wiki@historische-projekte.de for help.
