I am creating my own website through WordPress by way of Bluehost. As a member, I wanted to know if I am allowed to use or mention Blockgeek on my website? Secondly, there are some learning videos that are on Blockgeeks site for us to utilize and learn, will I be able to use a couple of these videos on my site as well or can I purchase them somewhere pertaining to Blockchain technology knowledge base?  Thank you
