I'm new to this site and is going to publish a story. Is the chapter editor based on something like HTML or BBCode?
It doesn't use BB Code and I believe it doesn't use HTML either.
I don't think you need to worry too much about the language it uses though, when I write a chapter in word, any editing I do ends up naturally converting to the format of the text editor. (for example, if I put a word in bold in MS Word, it is also bolded when I move it to Scribbly's text editor)
