  A high priority in light spectroscopy is to seek out and characterize various
types of non-$(Q\bar{Q}$) meson. The large quantity of new data now appearing
will present a great opportunity. To identify the non-$(Q\bar{Q}$) intruders
one needs to know the regular $(Q\bar{Q}$) pattern well; whole meson families
thus become a target for close investigation. A powerful discovery strategy is
to observe the same meson in a variety of reactions. Because mesons appear as
resonances, other dynamics can distort the signal in a particular decay
channel. Unitarity is the master principle for co- ordinating various sightings
of the same resonance. Much of the new spectroscopic information in prospect
will come from inferring two-body dynamics from three-body final states.
Conventional methods of analysis via the isobar model use approximations to
unitarity that need validation. Of all the meson families, the scalars should
be a prime hunting ground for non-$(Q\bar{Q}$)'s. Even before the advent of the
new results, some revisions of the `official' classifications are urged. In
particular, it is argued that the lightest broad $I=0$ scalar is a very broad
$f_0$ (1000). One unfinished task is to decide whether $f_0$ (975) and $a_0$
(980) are alike or different; several non-$(Q\bar{Q}$) scalar scenarios hinge
on this. To settle this, much better data
