Our eBooks are licensed for single use. By all means share with the guy in the next cube, but don't be a dick and upload them to a file sharing site. We're more than happy to do team and company licenses, just ask us for a quote. It's just Tom and John, and we're hoping eBooks, Video Tutorials and conferences will pay us full time, so file sharing and stealing our content (which is also stealing from the community) hurts us all.
