Hi Paul - I can well understand your disappointment and frustration, especially as layouts of the size of yours can have a complexity, and therefore interest level, not possible within the confines of the rules as they currently stand.
I did make a suggestion that MRJ might consider developing a set of rules that would accomodate people like yourself - and many others in the same situation - and perhaps run a new competion at sometime in the future - but don't mention again it to the guys in the other thread, as I think it would be fair to say that my idea was met with something less than unbridled enthusiasm!!! ....
Anyway, as others have said, I hope you continue with your project as it has some unique and interesting features.
