ABSTRACT 

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.
