If you really don't want to create a custom module, there is handbook page on creating a page to clear your cache that includes a snippet to add to a page using the PHP Input format and a refinement in the comments . Keep in mind, using the PHP Input Format is usually discouraged.
It wouldn't take many minutes to create a custom form with a clear-cache button that you can give your editors access to.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
