If you're unable to find the option to send a message in Bloomz, it may be due to the messaging feature being disabled for your class or group. Administrators have the ability to turn off the messaging or chat feature within Bloomz, which would prevent members from sending messages.

To resolve this issue, please reach out to your class administrator or teacher to confirm whether the messaging feature has been disabled. If it has, they can provide guidance on alternative methods of communication or consider enabling the feature if appropriate.
