When we consider the universal family of arrangements which are
combinatorially fixed, we have a fiber space over a moduli space of
combinatorially equivalent arrangements.   Each fiber is the complement of 
an arrangement.  The way in which these moduli spaces are glued together
corresponds to combinatorially properties of arrangements.  We pose
some basic problems and conjectures and answer to some of them.
