Comment 1 for bug 1308944

Going through these individually, I guess it is pretty much impossible to more specifically explain most of these, e.g., "A parent" is someone acting as a parent. So this should be fine for all of them (actually, is active always the default state?):

Customizing Membership States
=============================

SchoolTool has a set of built-in "membership states," which define basic
types of relationships between people and between people and groups. For
each relationship, there is a limited set of "meanings," and the school can
add custom states that act as specific codes for local use.

For example, in the Student Enrollment relationship, a school could create
both "Dropped out" and "Transferred." From the system's point of view, the
"meaning" of both would be set to "Inactive," and the two states are treated
the same, but to users the school, the distinction between the two may be
important and needs to be recorded explicitly.

In all cases "Active" is the default state, "Inactive" means that the
relationship has ended, at least temporarily. In each case, all the
built-in "meanings" must be used in at least one Title/Code/Meaning option.
