There have been enough questions to warrant a quick post.
1. Your header must look EXACTLY LIKE THIS:
SCREEN NAME: (type it here and be sure you included the colon)
TITLE: (type it here and be sure you included the colon)
GENRE: (type it here and be sure you included the colon)
2. You may have typed yours EXACTLY as stated above and still got bot-booted. So here's the trick: TYPE THIS SECTION INTO YOUR EMAIL BY HAND. That way, if Word is creating weird, invisible characters when you cut-and-paste, you'll avoid that problem altogether.
3. PLAIN TEXT.
It's hard enough to get through the door; I hate knowing that some of you have been tripped up by formatting glitches! :(
