Well, after a quick read through, you'll be getting a pretty good review from me. It probably helps that I am a fan of the Ravenloft setting and see a lot of use for it in that manner.
About the only thing I can say, over all, and assuming I didn't miss where you did this, I think a lot more advice could have been given to the DM on how to run such a game. Such as how to set things up and what to require of the players to make such a long term game successful.
I did see how you give a fair number of "pointers" to players of evil PC's on how not to disrupt the party unity, etc... Plus why they wouldn't.
I may have that review up by Monday. I'll link it to here whenever I get it done, as you asked.
