Your community profile can be edited here (you must be logged in to edit your profile).
Next to your name you will see a small pencil icon.
If the profile properties screen is not currently available to you below the "My Profile" module click the pencil to display it. Here you can specify your birth date as well as add an image. Images will look the best if you crop them to a square image, about 100 x 100 pixels before you upload them.
Your Master Profile is available for editing at any time just by clicking on your name at the upper right hand corner of LutheranEducation.net
