Johan is the founder of airliners.net and a forum administrator. He lives in Sweden and is a college student.
His forum username is : Administrator
Johan is the one you write to when you have a problem. Johan is the one who accepts or declines your uploaded photos (or at least his software).
Without Johan this site would not exist.
Now if you are wondering about Gary.....he's another admin, but he did not start this site to the best of my knowledge!
Hope this helps!
