Dear Tara,
I've just discovered that "spacing, new lines etc." disappear if you copy and paste from Microsoft Word (but it didn't happened with the old text box). You must type it directly in the text box (maybe, I've not yet tried), or they suggest me to copy and paste the text from Grammary (you can see its ad here in RR).
Someone here at RR thinks that a poem, a tale, a novel are works people create in a flash right into the text box, and they can do it again and again if it disappear when their upload is rejected.
