A Personal Profile is different from your user Profile. Your Personal Profile is a brief overview about you and can be seen by all those in your group and/or course.
Navigate to the Personal Profiles section on your course
Click on Personal Profile
Review the Example Profile
Review the Profile Guidelines and copy the header/titles in this topic
Click on Add a new discussion topic
Paste the header/titles you copied in step 4 into this new discussion topic
Add your responses
Click Post to forum
You will have up to 30 minutes before your Profile goes live and you can make any edits in this time.
