When you first register you are classed as a Professional Manager and can only manage one club. A confirmation email will also be sent to your registered email address.
To activate your account, click on the link within the email. If clicking the link doesn't work, try copying and pasting the whole address into the address bar of your browser.
If you do not see an email from Soccer Manager in your inbox, due to the overzealous filtering by ISPs our email may have mistakenly been sent to your spam folder. Please open your spam folder look for it there, open it and mark it as not spam.
If you still cannot find the confirmation email, you can add [email protected] as an approved Sender / Safe List / Whitelist email address.
If you confirm your registered email address and complete the tutorial you will become a Professional Manager and then be able to manage a second club.
