Can I link my earnings program accounts to a second HubPages account?

Unfortunately, you can only have the same AdSense account for both of your accounts. The HubPage Ad Program is created for each account, so you would have two that are unable to link together. You could earn more, however by separating your hubs between two accounts, so maybe this is for the best.

I would be interesting in seeing which account pays more.

You are not allowed to use 2 accounts together.

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.
