Hi Tim!
Courses that you can find in the forum are publicly accessible to anyone, and their accessibility and usage is covered by the E-Learning Community Guidelines on posting project files. You can check out the complete set of guidelines here:
E-Learning Heroes Community Guidelines
With that being said, you can try reaching out to the original content creator by clicking on their profile name or picture and then clicking on the 'Content Me' button at the bottom of their profile name if you prefer to ask for permission to use their files directly.
Hope this helps!
