Flint -
First of all congrats for your step-sons success! You should be proud of him, as I am sure that you are. Especially since you were not sure if he was going to graduate HS.
Was this a plan for him, or did it just happen to turn into a $200K + /year adventure?
Did you help him along with this, being the true marketer that you are?
Many of us are clueless in the endless opportunities there are for turning a great income these days, especially unique one like selling Tweeter...........
Continued success for him and keep him in line, that kind of dough for a young good looking kid can be very dangerous, but you already know that!!
