All I want for Christmas is ... our own institute's advent calendar!
Great to have you here! A very special Christmas countdown awaits you. Every day, until Dec 20, you'll find tasks that will not only add to your amusement, but will also help you get codes thanks to which you'll receive a prize at the end. It's possible to fulfill the tasks in home-office, but at some time you might need a cooperation partner-in-crime-in-house ;-)
Awesome if you'd let us know if you're planning to join: simply via firstname.lastname@example.org. You can join in at any time and then simply catch up on the tasks of the "missed" days.
The more, the merrier !!!
