You will see on your dashboard if you have any new messages.
When you click on the mailbox tab you will have the option to compose a new message or text as well as look at previous messages/conversations with students.
Students can reply to both email messages and text messages and you will see their replies both in your mailbox and as an email.
When you compose a message simply start typing the students name in the box to find the student.
When you compose a text make sure you sign off with your name or initials so the student knows who the text is from.
Your messages will show in your mail box and you can click on a student to see the conversation thread.
If you want to remove it from your mailbox click the Archive Conversation button on the top right of your message thread. If you communicate with that student again the whole conversation will be visible.
