everywhere on the web and the way to opt-out is detailed below. If you have a
Yahoo e-mail account or belong to one of Yahoo'smany Yahoo groups, this
probably applies to you. Yahoohas probably been tracking everything you do
online. Follow the instructions precisely to opt out of this.Notice the
important part at the very end. "Yahoo is now using something called 'Web
Beacons' totrack Yahoo Group users around the net and see what you're doing
and where you are going similar tocookies. Yahoo is recording every website
and every group you visit. Take a look at their updated privacy statement:
http://privacy.yahoo.com/privacy About half-way down the page, in the
section oncookies, you will see a link that says web beacons. Click on the
phrase web beacons.
http://privacy.yahoo.com/privacy/us/beacons/details.html That will bring
you to a paragraph entitled "Outsidethe Yahoo Network." In this section
you'll see a little "click here to optout" link that will let you "opt-out"
of their new method of snooping. Once you have clicked that link, you are
exempted. Notice the "Success" message on the top of the nextpage. Be careful
because on that page there is a"Cancel Opt-out" button that, if clicked,
will**undo** the opt-out. So don't reflexively click that button, or you will
undo the opt-out ! Feel free toforward this to other groups.
