So you would like to edit a contact in the portal?
To start, click on the 'Contacts' icon.
When you are in the 'Contacts' section, you will be directed to this page that allows you to simply click on their name from your contacts list. Make any changes you want to their account, such as link new pools to a contact, unlink an existing pool, or change the relationship of a contact to a pool.
When you are done with the changes make sure to hit the blue 'Save' button in the top right corner or at the bottom of the page before exiting.
