Files in the playground are for syntax testing only. NO GUARANTEES that this text will still be there next time you look!
Create your own file in the playground and play as much as you like!

If you're done with your play-testing, you can delete the page by editing it, removing the content, and saving the empty page.

If you have a nice topic for the Wiki and want to work on an actual article, do not create it in the playground. Instead you can create it under howtos: and put a “work in progress” sign on top.
