If you belong to ANY Yahoo Groups - be aware that Yahoo
is now using "Web Beacons" to track every Yahoo Group user. It's similar to
cookies, but allows Yahoo to record every website and every group you visit,
even when you're not connected to Yahoo.
Look at their updated privacy statement at
http://privacy.yahoo.com/privacy.
About half-way down the page, in the section on cookies, you will see a link
that says WEB BEACONS.
Click on the phrase "Web Beacons." On the page that opens, find a paragraph
entitled "Outside the Yahoo Network."
In that section find a little "Click Here to Opt Out" link that will let you
"opt-out" of their snooping. Be careful! NOT to click on the next button
shown. It is an "Opt Back In" button that, if clicked, will UNDO the
opt-out.
Note that Yahoo's invasion of your privacy - and your ability to opt-out of
it - is not user-specific. It is MACHINE specific. That means you will have
to opt-out on every computer (and browser) you use.
