What is the easiest and/or most cost effective way to publish mp3 audio files for download? I'm looking for sth with frictionless payments?

There are a number of ways to do this. For simple download products I use uploadnsell.com. You get paid directly through your paypal account.

The only issue you might run into is file size which is limited to 30MB. There are simple shopping cart plugins for most website content management systems (ex. Wordpress, joomla) that can sell downloadable products.

You can always look to publish through itunes. The to this is so many people have itunes accounts with credit cards on file.

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.
