This block is really easy to use. Just drop it into any area on your page, a global footer is the usual place. There is a field if you want to put a start date in but it is not manditory. Also you can display the copyright holder right after the year. But again this is optional.

Save the block and your copyright will be displayed in the recommended format.

Styling with css

I've wrapped the different segments in spans so you should find styling a breeze. There is a second template that mutes the text with some minor formatting as a demonstration.

If it works great for you please write a review. If not please put in a support request.
