If you want to easily communicate with all the users at your
school, you can create a group for your entire domain. This could be
useful for school-wide announcements such as testing schedule or
in-service day reminders, monthly events, etc. Instead of entering the
name of every user at your school, you can check the box next to Add
all users within this domain when you create the group.
users within yourschool.org will appear as a special entry in the group
member list, which you can remove and add back easily. You can apply
different sending permissions for this type of group as well.
example, you can have a school-wide group that only group owners can
send mail to – such as an announcement style where only the principals
and select faculty can send out mail, or you could create a school-wide
list that only members can send mail to – this could be like a
'watercooler' type of list where anyone from the school can send out an
email and anyone at the school can read and reply, or even a list where
any email address, school or non-school can send mail to.
your school, you will most likely use the 'announcement' style of
school-wide lists, where only a select few owners can send out emails
to the entire school.
