I don't think it really matters where ideas came from. What matters is people get what they want and need. The more we talk about this, the more people will get defensive, and the hotter this topic will become.
There are ideas on both sites that were borrowed from various places. There are other parts that look like they were borrowed, but actually might not be.
If someone asks Jeff, Hector, or myself to add another section, and if it makes sense (without cluttering the board) it'll probably happen. I could care less if he saw it on ClubGP or a Mustang forum, or just dreamed about it the night before.
We need to stop pointing fingers.
Both sites are a benefit to each other.
