Mel's right, but you don't have to insert the spaces between paragraphs by hand. I posted how to do it in your original thread, but I'll copy the advice here for future reference:
Highlight the text you want to post. It's not necessary to copy it into a new file, but I usually do so I don't inadvertently make changes in my main document.
Go to Edit, Replace. Type ^p in the Find what box and ^p^p in the Replace with box.
Press Replace all.
You don't have to manually adjust the spacing to single or remove the indent, as these happen automatically. Just copy the text and paste it in the message box over here. Check Preview Post for any irregularities, and if after you post you see things that need to be changed, use the Edit function here to do so.
Hope that helps.
