FAQ

Common questions.

This is a prompt collection event where participants will submit 3-5 short sentence prompts and then be able to view other anonymous prompts to be filled. A treat is filling the prompt as it is written. A trick is filling the prompt and changing the details. A trick cannot change the tagged characters and should have the two Bat characters tagged. Example: Jason is a witch determined to take revenge on Tim but becomes fascinated instead. A treat would follow the intent of the prompt with Witch Jason interacting with Tim. A trick would change the details and instead fill the prompt differently such as making Tim a witch fascinated with Jason or instead of Jason seeking revenge, he’s determined to get a date. A trick would NOT change the characters or theme of witches.
