One-time: Google Cloud → create a project → Enable "YouTube Data API v3" → Credentials → Create credentials → API key. Paste it here. Free; about 4 hours of chat per day at 8 seconds.
Members join only from the LAAPOA Member app → Live tab (turn it on in Member Management → Announce). Opening the chat link directly shows a "use the Member app" page.
Send members this link. Everything they post lands in this feed:
Excel or CSV with a header row. Needed columns: CID, DOB (date of birth), and the name as First + Last columns or one Name column ("Last, First" or "First Last"). Optional: Rank. Dates of birth are scrambled (hashed) before they are stored and are never shown anywhere. Uploading replaces the old list and signs everyone out.
