What is all the information that appears on the right side of my profile?
In the right column of your profile, all the things that you are the author of or actor in will appear on the right side of the website. Below that all pictures that you've uploaded or in which you were tagged appear. Connections are also made by adding keyword or manually creating links between content.
To remove the items in which you were author/actor. Go to my contributions and delete yourself as the author in the specific contribution.
