Someone seems to have discovered that by hoaxing my email address they can post viruses to this mailing list, so I have unsubscribed as "pepper at" and resubscribed as "steve at". Hopefully that will stop the problem. Regards, Steve -- Steve Pepper <pepper@ontopia.net> Chief Strategy Officer, Ontopia Convenor, ISO/IEC JTC 1/SC 34/WG 3 Editor, XTM (XML Topic Maps 1.0)
