Attached PDF shows the basic set up but years for students and parents are not current. In general:
parents20XY@lists.thet.net sends to all parent of the class of 20XY where XY is the last two digits of the year.
Same thing for students. students20XY sends to all students in the class of 20XY
A few other notes:
Many of the lists are limited as to who can send to them. For instance, parents can't send to the parent lists but Faculty and Admin can. Very few people can currently send to the TA-Trustees list.
The ovals represent "umbrella lists". These lists send to all lists below them. For instance, CurrentParents sends to all 6 of the parent lists under it. Students sends to all classes under it. Employees sends to all admin, faculty and staff.
Again, if you have questions, contact the IT office.
