Here's what we have to achieve in the final version: 

• Create groups to invite his friends into, in a way that makes sense (family, work, TGIF, and so on)
• Have his friends register for the app and join the groups they are invited to.
• Create activities that can later be used to schedule events with his group of friends.
• Collaborate with his friends to reach an agreement on what to do, when, and where.
• Have a few games suggested that they can play together as they wait for everyone to arrive.
