Where to add authors name?

Where do I add my name and link at in an individual template creation as in the red box below?

Templates/footer
and underneath

{$lang->copyright} &copy; 2002-{$copy_year} <strong><a href="http://www.mybboard.com" target="_blank">MyBB Group</a></strong>

put something like this

<br />
Design by <strong><a href="http://blabla.com" target="_blank">blabla</a></strong>
<br />

Would that then show across the original MyBB theme I didn't create? I'm using the default templates for this theme I created so when a user changes themes, I can keep all the imformation. Thank you Bas
