Greetings

Welcome and goodbye messages are off by default. Each group keeps its own templates. Enable them when you want Lucy to greet joins or acknowledge leaves; leave them off if you prefer a quiet timeline.

Commands

All require group admin:

Command	Purpose
/welcome [on|off]	View or toggle welcome
/goodbye [on|off]	View or toggle goodbye
/setwelcome MESSAGE	Save and preview the welcome template
/setgoodbye MESSAGE	Save and preview the goodbye template
/resetwelcome	Restore the default welcome
/resetgoodbye	Restore the default goodbye

You can also flip welcome and goodbye under Greetings in /settings.

Visibility and auto-delete

Option	Values (default bold)
Welcome visibility	public / private (ephemeral, only the new member)
Goodbye visibility	public only (the member has already left)
Auto-delete	keep / 30s / 1m / 5m / 15m

Welcome visibility and deletion combine. Goodbye can auto-delete on the same schedule.

Lifecycle gates

• CAPTCHA off: welcome sends after the join check when welcome is enabled.
• CAPTCHA on: welcome waits until the member passes.
• Quarantine or failed CAPTCHA: no welcome.
• Goodbye still follows leave events when enabled.

Templates

Templates support a safe Markdown subset, fillings such as {first}, {mention}, and {chatname}, plus buttonurl:// URL buttons. Invalid markup is rejected on save. Full rules: Message formatting.

Default welcome: Welcome, {mention}, to *{chatname}*!
Default goodbye: Goodbye, {fullname}.
