This is the entirely wrong place to come for legal matters. There has already been a good bit of misinformation. I'd suggest anyone with any concern or concern that they should be concerned talk to an attorney. For example, a copyright applies immediately, and no registration is required, but generally your suit against someone over an unregistered copyright won't get you where you'd like to be.

If any of this seems like it could maybe pertain to you, talk to an attorney.
