Forum:How to create an edit notice on Wikia?

How do you create an edit notice on Wikia? Edit notices are messages that appear when you edit specific pages, that can notify the user of what they can edit and what they cannot, or rules that they have to follow. I first saw a Wikia edit notice on the Children's Books Wiki, where two edit notices showed up (don't actually create the page, please). I would like to now how to create these edit notices. I tried simply copying the source code from Wikipedia, but that doesn't work.  CobraStrike  ( t )( b )(c) 14:22, June 27, 2012 (UTC)
