I found this on the ICOM 756Pro3 group on Yahoo's policy.
Yahoo is now tracking group members........but you may opt-out
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:
About 2/3 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, on the
left side of the screen, find a box entitled "Opt-Out."
In that section find "opt-out of interest-matched advertising" link
that will let you "opt-out" of their snooping. Click it and then click
the opt-out button on the next page.
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) that you use.
Additional note: You may have opt-out of cookies, but still be in for "web Beacons unless you follow this procedure.
You may use this and forward it to other groups or users.
