the one he is referring to only had 2 scots from the forums, as far as I am aware. The other two stopped by from the Americas. There's at least 6 people from the forum currently residing in Scotland though.
Halve that 16,000, as most of those guys probably aren't active regulars. Now divide that by three, as two thirds probably reside in the general forums. If the number really was so much higher, our meet-ups would have a much bigger turn out than three to four people from the entire UK.
