I had a look at the Forum's control panel - personal profile, but there is no option to change your e-mail address.
So I tried to change it at the C.Net website under Your Account. To open my acount I have to enter my present e-mail address and a password. After entering my credentials, I get the following message:
Sorry, I don't have this email address on file. Please try again with a different email address. I do not understand this as I entered exactly the same e-mail address that is used by the forum to send e-mails to me.
What is going wrong and/or what am I doing wrong???
