I have to monitors now and i need a free and good program to mess around witht he wallpapers and stuff like that, i heard about one here a few months back and i cannot really remember it anymore....
I'm not into it but, but lets say u want a domain like www.yourwebsite.com you can run a program that switchs your ip configuration so your domain is always related to your ip that way you dont need a static ip. But i dont know much about it just know it exists.
