- As any user, I should be able to create a call
- As any user, I should be able to see all calls // FOR NOW MAYBE CHANGE
- As any user, I should be able to respond the call
- If all call slots have been answered, automatically create the promise
- As any user, I should be able to see all the promises I made
- As any participant in the promise, I can create a fulfillment reflection on it
