Hackathon experience improvement: public "join" option #43
Description
Make it possible to express interest in the hackathon by "joining" it, which would make the user's avatar appear alongside others who have joined.
It would not be required to "join" to submit a project, but would be encouraged to help create community.
- Create a way to hook up users to hackathons (probably Sanity)
- Workflow to allow a user to join a hackathon
- Workflow to allow a user to unjoin a hackathon
- Query to pull all avatars for users who have joined a given hackathon
