The easiest way to protect your individual rights without spending a huge sum for a copyright is to print out all of your coding, pictures, web pages and seal it in an envelope. Place the sealed envelope into another that is addressed to you and use the postal service to deliver it to yourself, it will then have a cancellation date on the postage stamp. Put the envelope away, unopened, and repeat the process every time you update or make a major change to your property. The envelopes must remain unopened and should have a cancellation date that is before you post your product or website online. That way, if someone accuses you of infringement or there is any other attempt to hijack your property you have protected yourself in court. I know that a lot of writers use this method and can't see why it wouldn't work.
