The Potions and Snitches Tri-Writing Tournament (annual) :
This is an annual event. There will be three rounds of writing challenges, and like the Triwizard tournament each contestant gets points. At the end, the one with the highest number of points is the winner! 
Round One: Submit a one-shot for consideration, whether it has already been written and posted by you or a new one you will write just for the first task. Deadline is October 1st. Prompts may be requested by the author.
Round Two: By November 1st write and post a Halloween or fall themed story. Prompts may be requested by the author.
Round Three: Write a Christmas or winter themed story by December 25th. Prompts may be requested by the author.
Voting will be done after each round, and the final tally after December 25th. 
Winners will be announced January 1st. In case of a tie, a final show down round may be announced at the judges' discretion.
