User blog:MeredithAgnesPoe/Question?? I guess??

Howdy everyone! I'll keep this quick but I was wondering, would any of you be able to explain to me how to make one of those "don't edit this unless your an admin" box things? (Sorry, I have no idea what to call that). Is there a certain template I would need to use?

Sorry I have no idea how to properly phrase this. Thanks for your time :)
