Sorry to have to be so blunt but it costs a small fortune to prepare this stuff and those who pimp and steal others’ content need to pay for it. Besides, why should you pay to make other folk smarter? Let them pay for their own intelligence! This is a work in progress file, so we will be adding more data on a rolling basis.
