There is a new site called Client Check where you can check for initials and location of nonpaying reporters.  It's new, so there aren't many listings yet, but if you've been stiffed, please register and add the reporter's initials, location and CAT software so that we can all be more informed before taking on new clients.  Inform all scopists and proofreaders you know about the site.  The more participants, the better off we'll all be!
