Store your recipients' addresses as a contact for easy access. To add a contact, click the button with your profile name in the top right hand corner and select 'Contacts' from the menu.
To add a contact, click the Add Contact button. To edit an entry in the contacts, open up your Contacts panel, hover over your contact of choice, and choose Edit. To delete someone (ooof, tough break) from your contacts, do the same, and choose Delete.
You can easily add contacts from your contact list to a transfer by clicking on the plus (+) icon in front of each contact.
