Glad to hear from you and thanks for the comment I am glad you like the site. Sounds like you are from the South too or at least went to school there so thats extra points in my book.
1. Unfortunately there is not currently a way to increase the size of the vidoes on the site but if you click the video to go to YouTube then you can do it there in the lower left hand corner of the video viewer.
2. I have an IBM Thinkpad that is about 3 years old that I record those videos on and thats the wallpaper that came with that. I am not sure if there is a way that I can download the file and send it to you but if you know of one let me know and I will be glad to do it.
Just dropping by to say hi and welcome to the InformedTrades community. If there is anything that I can do to help you in your quest for trading knowledge please let me know.
