Welcome to our Discover Roundup, where we highlight communities doing creative and inspiring things with Discourse.

This month's theme: communities where people build things in public, then turn the hard parts into shared knowledge.

OpenStreetMap Community Forum

OpenStreetMap's forum gives mappers, data users, and organizers a shared place to maintain a global map. It separates broad talk from hands-on support: mapping and data questions go in Help and support, wider topics in General talk, regional work in Communities, and governance in Foundation. And new contributors get the help they need without having to know the whole ecosystem first!

Godot Forum

The Godot Forum serves game developers on the open source Godot engine, from first-timers to people shipping finished projects, and it handles both problem solving and show-and-tell. Posts sit in top-level categories like Help, Showcase, and Resources, with subcategories underneath: Programming and Physics under Help, Games and In Development under Showcase, Plugins and Tutorials under Resources. The discussion stays close to the core: code, scenes, exports, and playable builds.

Arduino Forum

Arduino's forum supports people building embedded systems, from classroom beginners to seasoned tinkerers. It's organized around the maker workflow: Development Tools for software and deployment, Projects for builds in progress, Official Hardware for Arduino boards and kits, Other Hardware for third-party boards and modules, plus Community and International spaces. It's a space to discuss electronics, wire projects, test, fail, and fix.
