Less posts could also mean that the cars are running good so less technical post,
and when questions are asked most problems well lets say 90% have already been covered and or solved.
That is why I think and is only my opinion that local meets such as the nano will become more involved in the future, not only do you get to meet people to chat about the cars you can see them in real life, hopefully more meets local members will spring up.
The dark winter nights will also see the posts rise I think.
