Marketing an audio file securely.
As a barely computer literate user I have observed the usefullness of turning to the contributors of this site with a problem. I have a product which I wish to sell on the web. It will be contained in an audio file. I was considering selling it through e-bay however that was simply a thought. Is there a safe secure way to compress and send such files to prospective customers?
Any suggestions gratefully recieved.
