At least my memory, of having had correspondence on the subject, seems reliable. Have a look at post #14 on http://forum.keypublishing.co.uk/showthread.php?t=97009. Whether anything in that thread is of use to you, vis a vis leads, I don’t know. For my part, I appear to have deleted the e-mail correspondence and a year later cannot remember more about it than I have indicated already. Sorry.
