What can I do to change my pCon.login user name?

Your e-mail address is also your user name. If you also have a pCon.update user name, you can also use it for pCon.login and for pCon.update. If you want to delete the user name and to use only your e-mail (in order to protect your personal data), please contact the pCon.login team at pcon-community-activation@easterngraphics.com.
