I got this today and sent it to about 20 people: "Marketers will soon be able to call you on your cellphone. If you don't want them to use up your time or money (your cellphone charges will still apply) call: 888-382-1222 or go online to http://www.donotcall.gov and register your number."
Oops! I probably got snookered by an Urban Legend. If you don't know about Snopes.com, I suggest you try it whenever you get email that encouragesyou to pass it on to everyone you know (even if the email is from your children or maybe especially from your children -- and other relatives). I seems that this has been circulating on the web for several years.
On the other hand, I called the number and registered my cellphone--and no harm was done. js
