"If your institution has enabled the Scheduler tool, you can sign up for any appointments that are created for your course using the Calendar sidebar. Appointments can include office hours, group presentation time slots, and lunch with an alumnus.Scheduler is an optional feature that may not be available to you in the Calendar."
After clicking the Calendar link, I cannot find where is "Find Appointment". How do I enable it and sign up for a group presentation time slots? Thanks.
