If you're an administrator with a Remind District Plan you can now message your entire district.
Head to the admin dashboard by selecting the district you wish to message from your menu on the left.
Click the messages tab, the text box at the bottom indicates that you can send a message to the full district.
In the composer you can also select the roles you wish to message.
Participants who wish to leave their schools should not text "Stop" as this will block all texts from all classes for legal reasons. Participants can text @leave to the @code for their school. Administrators can also remove unwanted participants from their schools from the school dashboard.
