Sandbox

This is the **sandbox** (copied and pasted from a previous Wikispaces project). It is for testing ways of editing. Please keep all editing tests here. Also, be aware that the sandbox will be cleaned periodically.

Things that have already been tested:

 * Code taken from Wikipedia's main page (most of it didn't work)
 * Four tildes work as a signature (e.g. 1242232423), " " tags don't.
 * If you don't want to use the buttons, double brackets still work as a link (e.g. Home)
 * Apostrophes don't work for **bold** and //italic//; instead you enclose text in two asterisks and two slashes, respectively.
 * You can upload images, for example: [[image:per]] Now, how to make them display as such?
