Create an online account
Some online account service providers allow you to create an account while adding it to Online Accounts. This allows you to manage all your online accounts from one application.
Click the icon at the far right of the menu bar and select System Settings.
Open Online Accounts.
Click Add account.
Select an account provider.
Find and click the Sign Up button or link on the page which appears.
Not all online account providers offer the option to create an account at this stage. If this is true of the service you wish to register, you will need to use an alternative method to create an account.
Fill in the registration form. You will typically be asked for some personal details such as username and password.
You need to grant Ubuntu access to your new account in order to use it with Online Accounts.
