"kland" is a reference that goes back to the Petit Computer Wiki.
It's not worth explaining beyond the fact that some users used it as an off-topic hideout.
One day, Lumage asked that a secret forum be created for similar purposes.
Random wrote the backend in 4 hours.
Lumage styled it after 4chan.
It grew as a private image host.
