Sometimes you need simply an area where you can test the functionality of this site. You have to show how to ask a question at training course. You want to try how to link an URL or an upload work. There might be a problem to format a question or answer. But you want to verify this before you report the error.
In all such situations you need not a reminder to the other users following the space Help. The question shouldn't enhance your reputation. You just want to test how something in answers works.
