OK - I'm going to post a sign-up thread for this imminently. I've stripped back alot of the elements I'd added and the whole process of designing this one has been very interesting - thanks to those of you who have given advice when asked.
I'm going to ditch the (Lynch immune) Conch element. Given that the tally is already going to be skewed dependent on whether the voter is a Big Un or Little Un I feel its best not to tinker with it any further... this time around at least. :)
