The Random Gists command randomly assigns gists from the open gist collections to all story points that are down to one available choice.  This command cannot be undone.

 

NOTE:  The Pick Random Storyform command follows the settings set up in the Spin-the-Model brainstorming tool.  This is important because Spin-the-Model controls whether or not existing storyform choices and gists are honored or cleared when this command is invoked.
