HubPages changed its publishing standards back in April 2011 such that affiliate links are no longer allowed. Here's an excerpt from their blog.
Affiliate Links: We no longer allow Hubs to link (directly or through redirects) to affiliate or commerce sites which are prohibited under the HubPages rules (e.g. Clickbank and sites that sell eBooks, promote dubious offers, contain a lead capture form, redirect users to unwanted websites, or contain pop-ups, pop-unders, or other features that interfere with sight navigation).
The sanctioned affiliate programs are Amazon, Google Adsense, the HubPages Ad Program, and eBay (coming soon). I use the first three and will probably start using the eBay program when it's available. Hope this helps.
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.
