As some of you who participated last year to RC3 (the Remote Chaos Experience, replacing the CCC Congress in times of pandemics), the "RC3 World" is based on the WorkAdventure software, a sort of 16bit JRPG enabling interactions through web links and jitsi chats.
Everyone is free to declare their "Assembly" and therefore contribute their map that will be part of a crazy network of maps (RC3World) where ppl will be able to interact.
The guide from last year has been updated, and contains useful information if you want to contribute a map to the RC3World.
This year: some scripting, a change in the badge API, and more detailed documentation, howto and "best practices" tips.
