Ich habe gerade eine lustige Feststellung gemacht. Nämlich, dass es gar nicht mal so unsinnig ist, wenn man bei einer Registration im Internet sein Geburtsdatum angibt. So bekommt man doch pünktlich zum Geburtstag eine Glückwunschsemail. Jetzt weiss ich auch wieder wo ich überall Accounts erstellt habe 
Mal schauen was da noch so alles kommt…
By accident I’ve found a realy nice service in the world wide web. Many sites such as forums, downloads, blogs or other need a registration. If you don’t like to name your private e-mail address you can use a temporary random e-mail address from temporaryinbox.com It generates a random email address which you can use for the given form on any websites. After you’re registred on a site with this e-mail address you can read the registration e-mail at temporaryinbox.com. Only put your temporary e-mail address in the inputbox at top right and click the “Go” button.
This is a very very useful service for spam protection. I like it!
Here a description from temporaryinbox.com:
A temporary inbox is a disposable email address, which doesn’t require registration and can be used to avoid spam. Use this email address in forums, lotteries, erotic sites or wherever. The spammers will never find out your private email address.
