How do you get paid after people start clicking the ads? and what does the number I see in my pic?

You should acquaint yourself with the site FAQ list. It answers both your questions.

If you're properly set up to receive adsense payments, you need to log into your adsense account to see where you stand and set up your payment options. Basically Hubpages just splits the displays with you, half the time they show your ads, the other half they show yours, you won't know whose is whose.

That number beside your picture is your hubber rank, 100 being the best, 1 being the worst.

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.
