First things first
Please update your profile. Say a few lines of introduction and upload a profile picture, so that the next step will look really COOOL!
The very first engaging activity is a nice challenge to interact with our @discobot, read carefully everything the bot says, try everything it asks you to do, till the bot grants you a certificate. Once you finish this very tiny but funny project, you will get a nice certificate like this below with your name and your profile pic.
To initiate this, send a message by clicking @discobot, to wake up the bot and start conversing.
