Designers, Fabricators, Assemblers and Users each have a unique and valuable perspective.
I suggest that IPC have one tech net forum where all four groups participate. Many problems have 4 different perspectives and we should not break up into 4 groups just to ease our mail load.
As the fabrication and assembly representative for my design group, I have to think about what users need and why. I would have to subscribe to and track each of 4 forums that would support my fields of view.
A simple example: Did the designer specify tin plated parts and eutectic solder plated boards for a SAC assembly process on 'green' hardware? Does that contribute to non-wetting, short life, whiskers or hogh voltage vulnerability? I defy you to resolve the question using only one discipline. We need all the viewpoints together to find the best solutions.
If we shorten our mail list, we lose vision and we become short-sighted.

I agree with Brian.
Things are better left as they are in my opinion.
