Continuing a discussion with @ljpp at our forum. Technically speaking the current description is ok, but otherwise I think it needs to be changed. I think that it is clumsy and can even be mislead a user to think that the badge is awarded on the first anniversary only.

Es gibt eine Lücke von 10 Jahren (2005 bis 2014). Ich habe die Badges einiger langjähriger aktiver Benutzer überprüft und bestätigt, dass einige Badges in den Jahren erhalten haben, die nicht dazu gehörten.
