Naming Conflict?

I’m thinking of calling my textbook posting site “Book Roll”. Finally one I like that wasn’t taken, or so I thought.

www.bookroll.com - doesn’t look to be active and the copyright and such I’m thinking is just typed in there - no real copyright registered or trademark registered.

My attempts at contacting the guy have not been replied to.

Even if I name this “Book Roll” and register the bookroll.ca domain name?
