Geekend is D-sek's big and (at least) triannual LANparty. Here you can play your favourite games, write some code or just have fun! The happiness and nerdiness will be through the roof!
Registration and more information.
Geekend has its own Discord server
It can be used to simplify communication during Geekend, but also to limit the depression generated by it not being Geekend.
