How Do I Add a Contact to My Address Book?
The standard way to do this is to select 'contacts' from the left menu pain and then
select the 'New' button in the top left corner. This will open a new contacts page
that you may fill out and save.
Another way to add a contact is to right-click on the email address when it appears
on the grey area of the received message and select 'Add to Contacts.'
