Update: IT Care has not resolved the issue wrt creating IVLE chat room. I will have to cancel the tutorial sessions for today.
The plan is to conduct our tutorial via IVLE chat, during our regular tutorial time.
But I have failed to create IVLE chat rooms for our tutorial tomorrow. IVLE refused and told me no slot is available and insists that I choose another date/time, even though the list of taken time slot shows otherwise. I have asked for help from IT care.
Please watch out this post for the latest update. Hopefully I will get the link to the chat room up here tomorrow.
