1) use my first example above, without the space between the brackets, for your line break command
2) I'm able to follow both my links; admittedly there is then a lot of info to wade through on the threads
3) Us lesser mortals can't fix our errors except by reposting the message. But if you contact someone like Joe, who has an editing button, that person might have time to add the line breaks for you. One way to get editors' attention is to put a message in the help section telling which thread needs repairs. The help link is at the top of the page.
