Please note: Changing user data is only possible if it is ensured that the user name is unique. With older accounts it might occur that a user name is found more than once in our system. During change of any data (e. g. bank details), this is being checked and you will be informed accordingly if appropriate. If this is the case, please enter a changed user name for safety reasons (like for example instead of "Smith" alternatively "Smith1950").
