I'd arrange it differently below CO, but I've been out for 9 years so I may be wrong.
Below the C.O. level:
Elder Caste:
Top Echelon Elders. "Heavies" at conventions, hobnob with CO's and DO's, regularly featured as speakers at conventions, top-requested visiting speakers for public talks.
Middle Echelon Elders. Assistants to upper echelon elders at conventions. Known by name by CO's and DO's. Well used as visiting speakers for pubic talks.
Lower Echelon Elders and New Elders. Run food service at conventions. Shake hands with CO's and DO's. Associate with ministerial servants. Sometimes give public talks.
Non-Classed Elders. Parking attendants and "clean up crew" at conventions. Say "Hello Brother" to CO's.
Associate with anyone. Rarely give public talks.
Ministerial Servants. Stage crew for dramas at conventions. Kneel before CO's and DO's. Groveling for that first public talk.
The Publisher Caste.
The Nun/Monk. Regular Pioneer, vowing to remain single to more fully serve Jehovah. If male, advances quickly to Ministerial Servant while waiting for the most prime skirt to say yes, if female diligently pioneers while waiting for that ministerial servant to say "let's get married so we can get in the sack". Cruises other nuns/monks at conventions. Well known by the CO if from a prominent family. Gives great announcements at the Service Meeting or great #3 talks on the Ministry School.
Good Publisher. Has boyfriend/girlfriend on a higher caste. Regular-auxiliary pioneers. May relate experiences at conventions. Gives very good substitute talks on the Ministry School.
Publisher. Friends with most everyone, even some vanilla fringe elements. Puts in 20+ hours. Has to be introduced to the CO.
The 'Other' Caste.
"A Witness". Babtized, Friends with everyone, even the CO knows his/her name. Sometimes goes in service.
"Oh, that's <so-and-so>". Babtized. Known by everyone in the circuit, even the CO. May go in service.
"Uh, that's <so-and-so>" . Maybe babtized. Known by everyone in the district, especialy his/her CO. Some of the "A Witness" sub-caste have been in field service with this person, maybe. The coolest person to hang with. (like Keith Conklin, right Slayer?))
then there's the rest of us.
