We have a classmate that is in/on the Class Profiles page and has never registered with the site.
However, he is NOT on the Missing Classmates page.
Shouldn't he be on the later?
His name is Lamar Jordan.

Which one of the following was used to determine missing? (numbers are mine to communicate here)

1 Consider Missing Classmates to be all Classmates who have not joined the site.
2 Consider Missing Classmates to be all Classmates with no email address entered in the system.
3 Consider Missing Classmates to be all Classmates with no street address entered in the system.
4 Consider Missing Classmates to be all Classmates with neither email address nor street address entered in the system.

Classmates do not show up on the MISSING CLASSMATES page if the "Missing Override" checkbox is checked, like it is on Lamar's "Manage Classmates, Enter/Edit Classmates, DETAILS" page.

Missing Override:        
Classmates appear on your Missing Classmates page based on the criteria you have set. If this Classmate meets your criteria and you need to remove their name from your Missing Classmates page anyway, check this box.
