Do unpublished hubs affect Hub Score?

No it won't affect your hub score..they just show the score of your unpublished hub in order to let you know that this would be the score of your hub if it is published..

I think yes.. I have seen my score going down when I have left hubs unpublished for a couple of days even though, I have been active on HP otherwise.

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.
