Compose your post using something like Microsoft Word. Save the file as HTML. Open that file in a a text editor like Notepad, then copy all of that gibberish into the FR post.
Thanks for the suggestion, GingisK. I do do that for my fiction work out of pure desperation. What I love about handwritten, over the gibberish, is that handwritten ISN’T gibberish. You format it and space it so that it’s as readable as the code we used to write in the 70’s.
