And of course I can't preview the test.
First, the page name: Wn4fz55iuamwacnt
Topic on User talk:Robkelk
Okay, that won't work - "PAGENAME" gave the thread name instead of the page name.
Maybe the root page name: Wn4fz55iuamwacnt
Still the thread name. Have I mentioned today that Flow sucks?
Top level page, maybe? Topic:Wn4fz55iuamwacnt
Once again, the thread name. Flow breaks magic words... which means I can't make that template after all. Aargh.
