The fastest route for everything is email:

What to include

• Bug reports: what you did, what happened, and your device/browser. A screenshot helps enormously.
• Challenge links that don't work: paste the full link you were sent — the score is encoded inside it, so the link itself is the diagnostic.
• General Enquiries: "General enquiries: include a clear subject describing your question."

We read everything. Short and specific beats long and general.
