Create a new page
You can make a new page two ways
A. Start With a Link
Start by making a link to a new topic. Using code [[like this]]. The link will take you to a blank page you can create.
The Rich-text editor, doesn't do internal links well. It does everything else well.
B. Start By Searching For a Page
If there are no results, you'll be prompted to create a page. If you use this method, be sure you link to it from somewhere.
Then, Move it Into Workflow
If appropriate, move it into Workflow with the menu beside the search, simply add "Prep:" and {{InPreperation}}. You'll be off to the races.
