My Contacts is where your contacts will be displayed. You can easily filter your contacts using the Search block. There is also the option to filter your contacts by information you have about them, for example mobile numbers for SMS, email addresses or Facebook details.
To send a new message to one of your contacts, click the Send Message link and you will be taken to the Message Box where you will be able to compose your message.
For information on how to delete and edit contacts, see Deleting or Editing Contacts.
