how do you host someones site? is it free??????where do i have to go?? please help me........im not that smart lol!!

to host someone's site, you have to have a domain name. No, its not free. It it was, why would everyone want one? :) You buy a domain name, then you explore your hosting company. Usually they give you subdomains where you can host people. You just have to have a domain name. Do you have one?

Some domain registrars provide free hosting.

For example, http://directnic.com will give you like 5 or 10 or 20 mb, i can't remember how many, but they put some banners on your page.
