A randomly generated certificate number has been added to the certificate one can obtain by earning a passing score via the online quizzes. The quizzes are designed for personal enjoyment and edification however some educators use them as a metric to measure a student's understanding.

For those instances, we have added a certificate number and a date/time group to indicated when the certificate was created. This allows educators to cross check their student's work to help ensure each has completed his/her own quiz. The certificate numbers are random, not sequential.

There is also a new wheel to help show how the hurricane damage potential increase with increases in wind speed.
