Sparky,
Everything should still be there. When you go to that Forum check that the dropdown menu (Top Right) says "Show all Topics" rather than "last 100 days" or whatever.
If not, you can always do a search.
Personally, I think that a picture of a center-tapped coil showing 120v to center (Neutral) on each side and 240v between the 2 "ends" would be easier to get the point across.
