We recommend that after you upload your students you send out a message to each group introducing them to CAS Manager. Once you are in the CAS group, click the "Messages" tab and then the green "Post New Message" button to compose a message. Be sure to tick the "Notify members via e-mail" checkbox so your students receive the message. Here's a sample message, feel free to edit and personalize:

"Hi IB Students,
CAS Manager is our new online system for the IB and CAS programs. I'll use the program to notify you of IB events, upcoming due dates and deadlines, and anything else related to IB and CAS. You can use the program to submit your CAS activities and documents.

You should have received a welcome email titled "Welcome to CAS Manager!" from noreply@eduvo.com. Click the link in the email to setup your password and get started. If you did not receive this email, let me know and I'll resend it.

Let me know if you have any questions!
[Your Name]"
