Look. Apple changed their info on email only accounts.Converting your .Mac trial account to an email-only account
IMPORTANT: If you want to convert your .Mac trial account to an email-only account, you cannot do this directly. You must have a full .Mac member, who has purchased an additional email-only account, include your converted account as part of their membership. Once your trial account has been converted, all your data files (except for your email messages) will be removed from Apple's servers. Other .Mac services, such as iDisk, HomePage, Backup, and Virex, are not accessible to email-only accounts.
To convert someone else's trial account to email-only, you must be a full .Mac member who has purchased an additional email-only account. Go to www.mac.com, click Account in the .Mac menu bar, then click the Email Account Management button. Enter the member name and password of the trial account you want to convert, then click Convert.
Print the email-only account information for future reference, then click Continue
