Of course, related with marketing! I'm only 17 and i need a credit card before starting investing, i've just got some domains, spent around 20 dollars and already got 150 dollars back lol
my best investment...... hmm thats a tough one... i once bought a pack of cigarettes and sold each one for a quarter at a party (.25x20=5-3.14=$1.86 +profit!)
These forums have been pretty good to me. I understant eh world of publishing a LOT more after the few months I've been here. another good investment was a friend adding robot for myspace.
