How to remove the copyright text for the T3 template

This is not a question, but an answer to one that may be frequently asked.

To non-destructively remove the copyright from the T3 template, create a rule in the custom.css file to set the display property for the t3-copyright class to none. So...

.t3-copyright {

    display: none;

}

If there isn't such a file in the CSS folder, create one.
