I think everyone here has pretty good points. The forum will never get new blood if they can't post, or their first posts are met with criticism.
For me though I think the issue is what dghii said - the cars are played out. Options for stock customization are extremely limited, and there just aren't that many guys who are willing out even want to do serious tinkering. I can remember one of my first motivations to get involved with the forum was to learn "what else can this car do". I feel like there used to be a lot of that, not so much at all now though
