What messages would I receive through Nixle?

Only authenticated agencies and community organizations can securely publish information. There are four types of messages; Alerts (many would refer to this as an emergency type alert), Advisories (less urgent need-to-know information), Community Information (day-to-day neighborhood to community-level information), Traffic (very localized traffic information).
