 Hi everybody! 👏
 
 We all at Public Lab 🎈 - learn, grow, work, brainstorm ideas, contribute together so why not share about our weekly goals and the awesome work we have done at Public Lab with each other, so we can support and collaborate with each other better. We have a Community Check-In each week, where every community member can share something about their work from the past week and about their current week's goal 🎯 . You are also welcome to share fun-fact 😄 , new ideas 💡 , your learning goals ☑️.
