I know that when I began funding author royalties were 70% for ebooks and 50% for physical. I also checked just a few weeks ago when I was promoting the site to a fellow author and everything was the same as when I signed up. Now I see that Inkshares has changed it to a flat rate of 35%? When did that happen? I did not see any announcements or other notifications. Is this change effective retroactively? Does it matter that the terms were different at the start of a given campaign?
