Are there any plugins for MediaWiki that would allow me to create a page that has a form at the top that when filled in populates tags further down in the document? Say someone would put a form with "Source Server:" and "Destination Server:" fields at the top. Once those were typed in it would automatically populate those names into the content lower so that when following the instructions you could just read the docs and not have to mentally replace things, and possibly mess it all up. I'm not looking to make pages that are permanent, just ones that can have values entered before they are followed. Any suggestions?
