Handling your bugs.kde.org Account
Your email address is your user id on bugs.kde.org. You create an account by having you mailed a random password. You can of course change your password later. If your email address changes, please also change your bugs.kde.org id so that you will continue to receive comments and questions by developers and other users (if you have not changed the email settings). You have created more than one bugzilla account over the years? Then you can mail the sysadmins and ask to have your accounts manually merged.
