5 cent surcharge for email to the USPS (update)
I'm not sure what anyone else has heard but this "new" 602P bill going through the House of Representatives (I think) bill would state that the USPS would get 5 cents for every email sent by anyone online in the United States.
Wanting to find out more on this, I went and searched on www.google.com for 'postal service email charge' and found this page (http://urbanlegends.about.com/library/blemtax2.htm) that clarified a lot of things.
Check it out. I found it a good read and maybe someone else will too.
