How do I track all the people I referred?

From the My Profile page click on Referral Link and select the Reporting tab.   This reports all the people (or companies) who are using your referral link. The ones in green are the active, meaning they are being paid or are paying virtual assistants.  The ones in red are inactive, meaning they created a profile but either do not have a job or have not hired someone or they have not initiated payment yet.
