Here's a grand campaign AAR that I started at matrixgames.com:

It's a combination of the 1917-1918 mini-campaign followed by the 1918-1923 campaign provided Whites survive the first part.
I hope this doesn't violate the usage terms of this forum and I would be interested in any comments, suggestions, and whatnot - this is my first AGEOD game and I'm still learning.
