Carl you make a good point and to add to that certain technical problems will never change. Such as you mentioned CA problems. This is a big one and all started when we started using CA as a finish. What happens and I said this over and over again that sometimes answers get watered down so much so that the entire problem is not answered. The reason they get watered down is that they become so redundant and people do get tired of answering. That is why I refer people to do a search. Many times that answer gets frowned upon but it is a valuable tool here.
In the segmenting forum I started a thread called "Why Blanks go Boom"
http://www.penturners.org/forum/f179/why-blanks-go-boom-110385/
When I started that thread my intention was to have a place where someone could go for reasons as to why a blank blew up and it happens so many times and the question gets asked how can this happen. How can it be avoided. I do not know how many people use that or find it valuable. But if it were stickied at the top of the forum it would be easier to find.
Might be something to look at.
