James,
That's pretty crappy! Well, it's a good thing that not everyone is in it for themselves! I'm in the belief of the e-publishing community helping each other out, but we should all benefit. People that are in this thing just to screw people over in order to make money are severely missing the point of community preservation. RPGing requires teamwork, and so does publishing RPGs.
I would personally like to thank you, James, for providing a cheap resource for us small companies to sell our products in. Not all of us can afford to get our books in print, so it's nice to have a vendor out there that cares enough about the community to do them a cheap service. Plus, there's some nice advertising as it is...that guy didn't need to do that!
You did the right thing

Lesser people (like my vindictive self, lol) would have went one step further and posted the reason for his departure and perhaps excerpts from the "spaz letter"

It's good to know you're professional, though....
Hmm...off topic a bit, but a slightly quirky thought just popped into my head...ever thought of "www.rpg-soaps.com" ? Detailing the latest scoops of fights, bickering, soap-opera-style gaming sessions...to keep all of us reality-tv-brainwashed sorts entertained?

Just an idea
