At the end of the day, Rob is organising it and can run it how he sees fit. You could always run your own on the lines you suggest.
Its not a criticism of Rob, its an observation based on when I go to a meet its nice to meet those I discuss and exchange views on the forum here with, not have 30% of the field made up with guests that I'll never see or speak to again.
Its just an opinion that's all.
