Also keep in mind that Congress is right now proposing a five-cent tax on each email sent from the US. In most versions of this legislation, bulletin board posts will be legally considered emails. I know this is true, because one of my cousin's friends knows somebody who has a roommate who works on Capitol Hill.
He also said that the email tax will probably pass right through Congress along with the Frequent Flyer Income Tax that is also in its final stages of revision. Since 120000 miles = a $12000 int'l FC ticket, Congress is setting the value at a dime per mile.
