Your profile determines what information other users can see about you in a course. It's also where you choose how you want to receive emails, edit default forum preferences and edit text.
When you're first enrolled in a course, the system creates a personal profile for you.
You can:
add an image of yourself, or an avatar, or any other image, which will display next to your contributions.
add information about yourself and your interests.
specify whether your profile should display your email address to others.
Click on account settings under your user profile and click on ‘Edit profile’ on right. Then, make any changes you wish and click on ‘Update profile’ at the bottom.
