We have no word limit: we'll accept any length.
Indentation and special formatting are fine and in most cases can be duplicated faithfully.
Multiple submissions are fine if these are less than 1000 words, but please include them all in the same file. (You're only allowed to upload one file, anyhow.)
For longer pieces, please submit only one.
If you're including artwork, please embed them in the document, as you'd like it to appear.
