When I was a child, I learned to do arithmetic by rote.I didn't understand what I was doing so when I made mistakes, I had no idea how to correct them. When I was very much older, the concepts behind the algorithms were explained.Light dawned, I went on to teach.
In the same way, the mark up language on wikitree was incomprehensible. I followed patterns and sometimes got the result I wanted but if I made a mistake, I was lost.
GAILE, has a brilliant gift for rendering the incomprehensible relatively understandable. She adds many G2G comments explaining wikimarkup.As they are often comments they don't even score a point.I find them invaluable.(I would love to see her explanations on how the 'language' works concentrated in one help sheet.
