When you click on the ‘Comments‘ interactive icon directly below your Username, it turns blue/white, and you will be able to read all of the comments that you have made — or under any other member’s profile as well.
If you want to add a personal avatar, a wall photo, or make a short profile statement about yourself or USC, simply choose Edit Profile which drops down when you click the ‘wheel’ tool. It also turns blue to the far right of your Username.
If you want to change your account preferences (password, privacy, notifications), choose My Account from the drop-down.
