I used the preview function last week as a test after copying and pasting Gerda's posting in the first time around and then tried a second time and saw exactly what I got when I hit submit...nothing.
I also did a test run typing something of my own from my desk top while being logged into the forum and then hit preview button and poof! It wasn't there in the preview screen.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
