I asked yesterday if anyone could help out and I've had a flurry of offers - what a kind bunch you all are. Thanks to the quick work of Kurtus Brown, I'm pleased to say that there is now an official forum for my rules here:
I'll be popping by as often as I can, and hope you can join us. This new forum should have a bit more functionality than BGG, and is, of course, purpose built for these games rather than hanging onto someone else's coat tails.
Also please drop by Kurtus' blog, The Forge and Brush Wargamer.
