Forum:Adding Templates?

Okay well...I was gonna add like some copyrightness for the images used in cards, for all of you who know about the DeviantArt rule you'll understand why. Well do I have to go and make a template just for this copyright, or can I use the coding from another template and just edit and use that?

Also if I were to add a template for this type of copyright, how would I make it via the coding? That "noinclude" stuff looked complex.
