Designed brings together an extremely diverse group of people from a wide range of cultures, languages, and experiences — that's a strength, and it requires everyone to do their part to keep the community welcoming, respectful, safe, and civil.
The full Code of Conduct covers encouraged behavior (being inclusive, giving respectful feedback, assuming good intent) and unacceptable behavior (harassment, intolerance, spamming) in detail. It's worth reading in full — it's what every interaction on Designed, from a Critique comment to a mentoring relationship, is measured against.
