If you look at any of the popular forums they are all centered on a specific vehicle, but they all have a healthy and active forums for people to communicate "off-topic".
The only thing censored are inflammatory remarks (and rightly so). To me it serves no purpose to restrict folks to only discussing the z32 here. This car has been around for 20 years, for the most part anything that can be done to the z32 has been in one form or another, there's not much new information to be consumed. Limiting ourselves in this way only serves to drive people away from this site. Why would we not let people talk about what ever they want in the general forum??
I love this site, it was the first forum I joined and I've met so many good friends here...I don't want to see it wither away to a husk of what it once was (which is already happening) because we aren't "allowed" to discuss anything else.
