And on that note I'd like to add that any group of people found to be using the forums to organise illegal activities will be promptly banned. The reason the "postwhore crew" is allowed to organise their cruises is due to them not attracting the wrong attention at their events... this includes "run[ing] against other cars" on the street.
Owning a Skyline dosen't give you the right to be a wanker on the street. I didn't know any of the guys in this group of cruisers (hell I'm from Melbourne, so I'm a total stranger) but I've met up with them a few times and cruised with them, and they're totally friendly and approachable. Granted I didn't rock up and say "omg I have a 300hp beast and I'll run you, and you, and you!".
