Thread:Extension talk:Cite/Mimic Wikipedia's Cite/reply (3)

you can move (i.e., copy) templates from enwiki to your site, but you want to pay attention to some things:
 * there are other extensions installed in enwiki. specifically, Extension:ParserFunctions, which some templates depend on.
 * enwiki templating is pretty complex, and many templates use other templates. if you want to pull a template from enwiki, you need to pull (recursively) all the tempalates that this template uses.

peace.
