Yes, of course! The most communities, forums, discussions, message or bulletin boards have been started and managed by normal internet users. That being said, creating a community is not something you go to university for and get a kind of degree.
I, personally, have studied computer science. However, during years of my study, I have not learned how to create communities.
I can guarantee that most people who start forums or communities start it without any experience at all. You gain experience while you create and manage your community.
