What I did , when I first started was spend some time , well actually a lot*of time, going through different threads and reading the many posts.
You would be surprised at how much information exists on qq , that answers the many historical quad questions you have.
And even now I will sometimes go through many posts to find specific info regarding something I did not know prior,...and I come from the Quad era .
And even now I notice my thread , (check similar threads below) , almost duplicates doity's.
So somehow I missed it.
*I mean sometimes a whole day or week.
