The account section has all the pages that are related to your personal account.
It allows you to take a look at your career options, in case you want to fund a new team, resign from your current team or apply for a job elsewhere.
You can also change your settings, or buy supporter in the shop. In the private life section you can buy shares from other teams to become a shareholder of the team, and also change your salary.
The mailbox allows you to send mails to other managers, and the helpdesk allows you to contact the Pitwall administration in case there's a problem with your account.
