I agree!
They are an excellent reference.
Often times I remember who made a specific quilt or started a thread about a specific technique and then can go to their listing to find what I want.
I often refer people to past threads, whether mine or one that someone else started.
Just today, I was looking for two from other members, and yes, all gone.
Likewise many of my own have gone poof!
Too bad ... and it would be nice to have them back, but I have my fears ................. they are gone into never-never land.
