Now that you've read all about editing your profile, you may want to know how this information is displayed to others. Even though it may be called a "Public Profile", the system is set to require a user to login before viewing the information, so it really is limited to community members.
Some of the profile information is displayed next to each of your posts in the system. The full profile can be viewed by clicking on any user's name in the system. The profile screen has three sections: an overview section, and "Options" section and an "About" section.
The overview section:

This section shows basic information about the user.
The Options Section:

This section will let let you take specific actions related to the user who's profile you are viewing. Users only see the "Edit my profile" options for their own profile.
The About Section:

This section shows the user's bio and any recent activity from the user.
