Details TBD, but provide a more complete and finalized experience for how editors can set goals as groups or individuals through event registration and see progress against goal. Maybe also way to promote goals for others to join or duplicate.
###User stories:
As an event organizer, I want to be able to set a goal for my event, so that participants are motivated to join and contribute based on the goal, and so that I can have a clear story of the event outcome based on the goal.
As an event participant, I want to know how my contributions help accomplish the goals of the event, so that I can understand the impact of my edits and of the event overall.
As an individual editor, I want to be able to set goals for myself and track my progress against goals, so that I can edit with clear milestones and boundaries that are manageable and rewarding.
As an individual editor, I want to be able to discover goals set by other editors or groups of editors, so that I join in these challenges myself or be inspired to create a similar one myself.
