Starting now, you can give acorns to each other.
What are acorns? Well, they are a fun thing that you can collect and share with your friends on ATP. Click on someone's username and then click on "Give acorns to [username]". Giving someone acorns is a very special thing and lets them know that you appreciate them.
At some point in the (near) future, I will have extra badges and special microbadges that you can spend acorns on to receive.
What if you don't have acorns to give? Well, soon I'll have ways for you to get acorns from the system.
