Do we earn from ads displayed on our profile page, or only on our hubs?

So long as you have activated the HP ad program and approved for Adsense then the answer is yes. Whatever ads are placed within your account you get paid for them.

Your account is a subdomain, that means it's a website within a website so whatever happens in your subdomain is yours.

The questions and answers, forums and other HP pages belong to the main website (HP) so you don't get paid for those ads, HP does.

If you have gotten your affiliate earning accounts activated such as adsense, then yes you will earn from all ad's displayed I believe, but if you haven't then I'm sure you get paid nothing.

Try asking the question in the help area located on the upper right corner of the screen, that might help you more accurately.

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.
