OK, now I suspect you're a troll, and that tsetse-fly is some kind of sock-puppet, and that you really need to think of something better to do with your time than this.

update: No, now I come to look at it, tsetse-fly has been around for a while and made some sensible comments, so probably isn't a sockpuppet. mellow, on the other hand, is 14 days old and has mostly posted rubbish.
