While I do understand your views, you really should start coming to term with the fact that the old site is gone, will never come back.
I do not know where you are on your PCa journey? I am well into mine and spend less time here and relying on here than I did before "the change", thank goodness.
But, for newbies this is the new site, and this is what they will use and probably get as much use and information and support as we old gits did from the old site. No need to adapt as they will not know war was before. You and I maybe be used to vinyl, the newbies are onto CDs mate.
Us oldies do struggle with new stuff, but we have to learn and adapt or we lose ground with modernisation. Hey, you are not still boiling a kettle on a gas ring are you, keep your food in a pantry, wash your clothes in the stream? Or buying your fruit and veg in lbs?
