I'm sorry for speaking up on this touchy subject.....
They have a lot of non-ZR-1 archival info that they recently re-enabled which could be of use to us as eventually we will have some regular C4 issues where giving a link to an alternate reference material could be of assistance. I'm not trying to be obtuse, but chances are due to shear volume of traffic & membership one could expect that there could be more info to be mined? This is JMHO where looking for information is the only objective, links are always helpful.
As a new comer to our registry and C4's in general, I sort of need all the help I can find.
Peace

Tom
