Great link to do your search on Google. After the link, add your key words.

To test this link, I first typed "bingo". Google immediately found the thread where a fellow forum member solved my turntable problem by beginning with the word Bingo.

My second search text was "fix the hump" in which a fellow forum member gave me the advice that I needed to solve my derailments and unintended uncouplings on my old layout.

Gonna leave this link here for my own future reference and that of others who can no longer wait for our host to update the failing software.
