Re: Filemanager confuses me
Not sure if you are listening to anyone trying to help you?
Stop thinking about creating sub domains, folders, or anything else and concentrate on making pages.
You already have a page called index.
Now make a page called 'united' and publish it exactly the same as you did for the index page. don't change the folder, just publish to public_html
Do this for every page.
There is no need at all to create folders in your CP, in fact your best bet is to stay out of your cp until you have finished your website.
Don't aim for success if you want it; just do what you love and believe in, and it will come naturally.
