So,

If you go up to your profile picture, and click on the first option that drops down: "View Profile": you should get to your User Page for the wiki. Go to the URL at the top, from there, and add "/Sandbox" to that, and you should be able to access it.

Your Sandbox can be edited freely using the normal code for pages and whatnot, and remains accessible at all times while logged in, even though it doesn't show up as a searchable page on the Wiki itself. You can even keep multiple different Sandboxes operative at a time, by adding a number after the /Sandbox in the URL.
