I'm sorry to have missed previous emails, I can't think of a reason I
wouldn't have received them. To your points:
I don't know about exclusive video hosting, we get a lot of people asking
for it...perhaps later when we release more videos we could give you an
exclusive one.
About the Q&A, we just did something similar on Warcry:

I'd be happy to support the Curst Darkfall site somehow if we can come up
with something. Unfortunately we're always swamped and our options are
pretty limited. Let me know what you think.
