In the terms and conditions page, it says:
“One needs to be registered as a participant on CodeChef SnackDown 2016 to refer friends and colleagues.”
I understand that it might be something like “If you haven’t gone through the experience yourself, how can you suggest others about it”. But since the first four rounds are going to be just like any other contest, anyone who has participated in a contest will know what to expect and can tell others about it. I’d like to request @admin to remove that rule so that someone like me who didn’t participate in Snackdown 2016 can have a shot at getting some goodies.
