I guess this is my perceptual failing. It is difficult to make changes to a post because the the text in the edit box appears so very differently formatted from what is shown in the thread. It took me an hour to get together one post on genetics just a minute ago. I re-edited probably 10 times. There may still be boo-boos, but I gave up. I've tried cutting and pasting from a desktop editor like UltraEdit, but text formatted the way I want doesn't always transfer over well. Suggestions?
