The stdlib team is active in the chat, and public messages are the best way to get timely help—no need for routine @-mentions. Asking questions in public is the fastest way to get a response, as more people can help, plus it's likely that someone else will benefit from finding out the answer to your question. The stdlib Code of Conduct applies to all community spaces, including stdlib's Zulip. Should you encounter an issue, Zulip's reporting tools and our moderation team are available.

Music Lab by Code.org is a Blockly-based experienced, built for K-12 education, at https://code.org/music.
It's open source, and we wrote some technical documentation at https://github.com/code-dot-org/code-dot-org/blob/staging/ap...
There were a bunch of interesting aspects to this project. One of my favorite things was developing the user programming model.
