Now I remember! Syet! Those were the days of jag-a-log!

International Order of the Rainbow
http://www.iorg.org/

DeMolay is an organization for young men, similar to Rainbow for Girls, that teaches leadership and respect towards others, in addition to many other lessons. They are also involved in community service.

Job's Daughters is an organization for young ladies, also similar to Rainbow, but they require that their members have a Mason for a relative. Their teachings are similar to Rainbow's, but based mostly around the lessons from the book of Job.
