Hey Ben,
It's just that I feel the new design is way too "confused". The old forum was based on an elementary scheme, it was far more "easy" to use or "grasp".
STILL, you did an outstanding job, really. An amazing job.
Try to make some details more "Alpha Flight-ish". For instance, when you enter in a sub-forum, I just don't like the "postal letter" avatars marking each thread... I would change those with maple leaves.
Also, there should be more red...
