By registering as a user of WWWis I will be able to tell you of new versions. Also I can feel quite smug about how many people are using my software. Don't worry I wont give the list of users to other people. If your browser doesn't support forms then just simply mail me
Warning - Clicking on the submit button will subscribe you to the wwwis mailing list - I use this this to announce new versions - expect a message about every blue moon.
