Hi Cindy Camillucci. If you can go back to your homepage of grokker.com, there should now be the option on this page to join the challenge. I apologize, but there was something turned off for SIG users to see these challenges. That has been updated, and the option should now be available. If you still have any issues, please email us at support@grokker.com and we will continue to investigate.
