By more carefull do you mean scan it with anti virus software before I open downloaded files? I do that.
By more careful do you mean having software that acts as a watchdog to P2P downloads which has Limewire in the list of P2P networks? I have that.
By more careful, do you mean, as new people to this media, we unfortunately will sometimes have to learn by experience of the many dangers that await us by those who say they are offering one thing and instead, offer something entirely different? Guilty as charged. But, as in life, those who learn from their own mistakes are ususally likely to be more understanding in their dealings with others.
Seems like even message boards are not free from snipers these days!
