When in edit mode for the hub you want to add a summary to, look around within the position of the capsule bars, you will see 'automatically count summary' check box, uncheck it and then type in your summary as you want it to be. If you didn't unchecked the box, hubpages tool will automatically take the first part of your hub as the summary. I hope this answers your question?
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.
