I can't believe still no one has replied to this. how is it possible to get answers if no one replies?
the answer to this one is: you have to use Microsoft Front Page. "Open Web" to the url of the sharepoint site, then edit the default.htm page. once it finally loads, you can double-click on the Events section which will invoke its properties, allowing you to specify the filtering criteria.
I sincerely hope someone of need finds this. /jb.
