I saw an article about turning WordPress into a contact manager last Friday. This is interesting and is in some ways a parallel effort to the Prologue theme in that it seeks to extend the WordPress engine into another area.
However this is not strictly speaking a theme. Rather it is a set of instructions that make use of a number of plug-ins. It looks to me as though the idea explained here could be quite simply adopted to create the review pages I have been meaning to set up for some time.
