Here's how to refer your friends to the program:
Click your profile on the top right side
Click Invite Friends
3. Choose which tab you'd like to enter the details in (either get a free Python course or get a raffle entry to the yearly Cisco Live free ticket)
4. Use the links provided or enter your friends' email addresses.
To check if anyone has signed up and if you've completed the required number of referrals, you can simply go back to the tab you chose (either Python or Cisco Live).
