I cannot log in even after entering my login ID and password for CanvasWorkspace.
The registration may not have been completed.
Check if the registration confirmation email message from CanvasWorkspace arrived. If it has arrived, access the URL in the email message, and then complete the registration.
If the email message has not arrived, check if it arrived in your junk mail folder or if spam filters have been set.
For details, refer to I registered with CanvasWorkspace, but the email message did not arrive.
