Couple Changes to the C4 Forums

[Rob]

Please note that the C4 forums and their threads have shifted a little. All modification and technically related C4 threads have been moved into the new C4 Technical and Performance forum.

The C4 General Discussion forum should be for topics that are related to C4s, but not necessarily technical nature. The C4 General Discussion forum is the perfect place for owners to introduce and get to know one another.
