Not having mentioned it earlier, it's time to mention the silly things that copyright laws and their enforcement can bring.
Read the following article for the debacle on the new Harry Potter book publication and sale where 14 customers who bought the book (unknowingly ?) before the official sale date were asked to stop from reading it further, return the books & notes prepared, declare name & address & phone-numbers of people with who they had discussed it and so on and so forth !!
Isn't there something called a "right to read" ? Or am I missing the whole point of the people on the "other" side ?
