Entering Schedule for tutor

The information link on the profile page says that to host a conversation you need to enter time on your schedule, but I cannot find where to enter my schedule.

Please explain.

On the Exchange button at the top of your screen, select Teach on the drop-down menu. You’ll see a calendar. Click on the date that you wish to modify.

An important hint: Don’t forget to set the correct time zone on your profile.

Thanks for the help.
