How to license and copyright your work?

No, because copyright is all about who lawfully owns something, you'd have to go through the U.S. Copyright Office if it's that big of a deal.

Register your site with the U.S Copyright Office.

@Ben I'd rather not. Is it possible to do it yourself?

@Keto Z How does that not break the purpose? I don't want anyone to use my work unless I authorize, including any government. Also I posted a reply earlier that somehow has been removed.
