The chat and follow buttons were replaced by the small gear icon. My test users loved the chat button, and used it right away. I don't think they would notice that the chat button is a couple clicks away using the gear icon.
great! whatever you guys can contribute back would be greatly appreciated 🙂
EDIT: If you guys need a hand anywhere, feel free to send us a message. I'd like to see NodeBB support multiple front-end frameworks, so anything I can do to bump that progress along - you know who to reach out to 😉
