[SL] re: 2B organized

[Neal Carpenter <ncarpenter@teachers.org> (by way of vanessa colella)]

  I agree with Christopher Berg.

If we each put [SL] at the beginning of each subject, it would not only
help us all in sorting the messages, but would provide a nice example of
the kind of general behavior developed not by a universal rule, but by
some feedback from individual responses.

How fitting for _this_ list server.
