So sub.domain.com is really at domain.com/sub
OK, this is a really basic newbie question. I am making a website and would like to arrange them into subdomains: a.myweb.com, b.myweb.com, etc. Inmotion is hosting the website. In creating the subdomain, they ask where I want the root folder for that subdomain to be. How is this done usually? Should I make a folder a, b, c, etc. under public_html and use them as root folders, or somewhere else?
