Yes. The FReeper beeper has been around for a long time. Click on the the little speaker icon at the top right of the "browse" page.
I seem to remember something about this, when it was instituted, but since I was then a Webbie and it didn't work for WebTV users, I never bothered about it ( actually, I forgot all about it ), by the time I got my laptop.
Thanks for the info. :-)
