John would be the best one to ask.
But I believe it has to do with a reward for those that have done something commendable concerning the forum or collecting Harbour Lights.

Sthompson became one for his years of supporting "retired at retail".
Oseabee became one for remembrance of a great guy and a fantastic forum participant.
Bob M and Monobo became one for their years of massive participation. Only St John has more post then them.
FredKuhl, JtimothyA, Rod Watson, WackoPaul and Dave H for all the support they have given to the forum and other Harbour Light related items.

And JChildester was a Saint from the old AOL days before this forum was even started.
