You get copyright on something as soon as you have anything that is 'obviously something in visible/material state' created by you (ie. a website template).
Copyright is only available on material things (including virtual ones) but not for abstract things (ideas, ideals).
In some countries, the (c) symbol holds no value. The perfect copyright notification would be "(c) Copyright by [name] (year)". In most countries, you lose copyright after 60 years after your death.
Also note that you're protected for free by the Berne convention in 1886, which states any artistic or literary work. In the world, 163 countries have signed the treaty (as far as I'm aware). The US (I'd daresay once again) is the only one working under the convention that does not adhere to the rules: Copyright protection should be free. In the US, it costs money to register something to be able to recieve statutory damages. In other words: the copyright claim is rather useless in the US.
