Part Number
This is the part number of the episode in serial or multiple-part stories. Some authors prefer to submit chapters individually, but this should only match the chapter number if you do that consistently.
If you are submitting only one part, and the story is complete, enter a 1 in the box.
Some authors like to post an introduction, or prologue, so the number 0 is used for that purpose. If you ARE submitting an introduction, you must submit at least the first part of the story at the same time, but, do it with separate forms and uploads if the parts are to be posted separately.
