Adding a copyright statement

Yes, you should fork an editable copy of your template if you haven't already and then add your statement to your template's footer.html file.

If you were using the Blog template, I'd insert something like this just before the script tag:

<p>© <span id="year"></span> {{title}}</p>
<script type="text/javascript">
document.getElementById("year").innerHTML = new Date().getFullYear();
</script>

However, if I were you I wouldn't do this, copyright statements provide little benefit and are unaesthetic.

Please let me know if you have any questions about this or anything else

Great, thanks for the advice.
