Ad-hoc Group (number icon)

• Created when you pick users individually and send a message.

• The avatar shows the member count (e.g., 80).

• Static membership: if a new student joins the class later, they won’t be added automatically—you must create a new group.

• Best for short-term or targeted threads (a small project team, a few parents, specific staff).

How to create: Messages → Send message to user → Select recipients one by one → Write message → Send.

Class Group (people icon)

• Created via “Send message to group (specific class)”.

• The conversation is linked to the class roster.

• Automatic membership: when students jointhe class, they’re added automatically.

• Ideal for ongoing class announcements, homework reminders, weekly plans, and general updates.

How to create: Messages → Send message to group (specific class) → Choose the class →  Write message → Send.

Which should I use?

• Choose Class Group for anything class-wide and continuous—no manual updates and no missed messages.

• Choose Ad-hoc when you need a limited audience or a temporary conversation.
