Before I started researching the different marketing strategies on agtalk, I didn't know the difference between a put and a call.  Different posters have put up links to collegiate marketing classes and other resources that have helped me immensely!

All the reading and studying help alot, but real world experience is priceless.  I would also like to thank everyone who takes the time to tell everyone not only what they do, but why they do it.  Even if it doesn't fit my situation, its still great to learn from.
