How do we calculate the order of recommendation on Facilitators page?

We take into account the following factors:

-years of experience
-past attendee ratings of public and private events
-total number of events held
-total number of ratings from attendees
-if the Facilitator holds a Certificate of Practice
-if the Facilitator holds a Certificate of Attendance
-if the Facilitator is a certified Management 3.0 Content Creator
-if the Facilitator is an Agility in HR by Management 3.0 Facilitator

If a Facilitator does *not* have a profile photo then the profile is not visible on the list of Facilitators.
