Here is what I want to accomplish:
Inside of a Wiki Library, user says they need a new page and creates one using the [[ ]] syntax. Then when the user clicks that new link, they are asked to create a new page. Instead of a blank page being created, I want the page to have a layout and fields like
Enter Description Here and
Select a Topic with a drop-down menu.
I was able to create a content type and page layout but I'm not sure how to get the Wiki to use the new page layout instead of the old one.
