The Sandbox web is the sandbox you can use for testing. Everybody is welcome to add or delete some stuff. It is recommended to walk through the TwentyMinuteTutorial to get a jumpstart on the KreisQuality tool. A good rule of thumb is to add at the end of the page and sign and date it with your WikiName.
Come here and try things out, make changes and get a feel for how this works.
