Can someone tell me how to use the formatting functions described at the bottom of the Submit Article page?
It seems when you use the Page tag, it automatically create links at the beginning of the article, but I don't understand how and what to use to create text for those links, etc. I've played around with it for an hour or so, but I was hoping someone here might know how to use and be able to explain it with some details.
I'd appreciate it.
