HOW DARE YOU!
This author is obviously in the middle of an identity crisis. Today he's god! Tommorrow he could be a carrot peeler.
No one likes being flamed. It happens though. I once had a man yell at me for fifteen minutes because I ran across a corner of his lawn on my morning jog. Apparently I'm a trouble-making hooligan.
I run across that corner every day now.
Okay, I'm not sure how he's working...but...
Sometimes authors finish their stories on one website...and then submit them to another on the condition that the 'new' website releases chapters once every week, even though it has been released in its entirety somewhere else. It's a fairly common practice.
Still, regarding your e-mail and how you approached him...its tough to judge when we're only getting one side of the story and no e-mails. He may have misunderstood your wording. Then again, he might be a self-serving pig headed goon. Takes all kinds. He might be getting harried by many e-mails on the subject, and you just got the short end of the stick (and perhaps the other end is up his...ahem). The way you've described it he simply overreacted.
Hey, authors don't need to have social skills to write good fiction. My advice: shrug you shoulders, mutter 'ass****' and don't let it get to you. I'm sure he was that 1 out of 100 exception you thought you'd never have to talk to! I'm sure the 99 other authors would have been tickled by any interest in their story.
