I am an entrepreneur currently designing a business model which involves selling online forum memberships to university students looking for secondary resources for their courses.
I would like to compile both original material of my own and free educational materials available through the internet which "may be distributed and copied" as long as they are for non-commercial purposes.
What I am wondering is if I can post these resources on my forum without constituting "commercial purposes," where people simply share resources and information anyways. I wouldn't be selling the resources, but rather I'd be selling access to a forum which includes the resources.
If this is doesn't constitute "commercial purposes," then am I allowed to include the fact that such resources are available on my forum in my advertisements?
Is this idea legal? If not, then what happens if people who purchase membership chose to provide such free materials? They would clearly be doing for non-commercial purposes.
Thank you everyone.
