The quest uses the voting types of Write In, and Choices as the ways of voting, and will define what voting system is currently in use at the end of the post.
When you write in a command, like "[X] Create a giant donut", the character will then try to accommodate the action. Certain actions take rolls of dice or coin flips to succeed, while others will be difficult or even impossible given your character's personality or abilities.
When offered a choice though, the only choices will be displayed in text at the end of the post.
