Thanks again Paul, great stuff!

I have used R-maps mainly as a prep tool for mystery and fishtank games, before/between sessions, to make sure my situation is sufficiently primed for action and intrigue (but completely missing out on the theatrical aspect that Paul mentions).

Re: editability, I have tried a couple of times to make R-maps in sw/apps like Visio, The Brain, etc.. It would be sweet to be able to drag things around to make room as the R-map evolves. But I never found one that allowed you to label the relationships, and that could do asymmetrical relationships. Maybe better tools are available now.
