Here's a small new feature that makes a huge difference: notifications.
Now when you're logged in, there's a smiling character next to your name. When you get new comments and likes, a shiny number appears. Also, when new Things land on the #hashtags you follow, you'll get a notification.
Imagine someone just commented your newest design and the notification pops up on your screen. How many seconds could you bear the excitement and not go see what they're saying? If you're like me, you're already rushing to see what's there.
So go on, sign in to Tinkercad and take a look what others have created for you. Enjoy giving and receiving comments and likes.
