Group owners and moderators can create customized, prewritten messages, called notices, that can be sent to group members for various reasons.

Notices make it convenient for owners and moderators to send commonly used messages to members under different circumstances without having to rewrite the text each time. In the case of a member-initiated event, such as someone leaving a group or joining an unrestricted group, having a notice makes it possible for a message pertaining to that event to be sent to the person automatically.
