Do I have to greet guests who join my room?

Yes, if you're on hourly pay. When a new guest joins your live room, the Studio shows "… just joined" with a timer and a box to type your greeting. Write it in your own words — there are no ready-made lines and pasting is off.

• Greet them within 2 minutes: any message in the public chat, or a private message to them (and say hi out loud too).
• If you miss it, those 5 minutes of hourly pay aren't counted; Wallet → Activity shows "didn't greet a guest in time".
• A guest who leaves before the time is up needs no greeting.
• The same goes for messages: when a guest or the team writes to you (in your room or privately) while you're live, answer within 2 minutes. A missed answer shows as "didn't answer a message in time". Messages from other listeners don't count.

Call earnings are never affected by this rule.
