Profile Info Screen
The Profile Info Screen shows details on a particular Interest Profile. You can get to it from the Profiles Screen by tapping the Info button for the profile.
On this screen, you can change the profile name, export it to a file, or delete it.
The Lock switch, if turned on, will prevent you from adding new topics to, or deleting them from, the profile. It doesn't prevent you or NewsBrain from adjusting individual topics - you can individual topics on the Topic Info Screen.
Export to iTunes will create a profile document that you can see when you sync with iTunes (in iTunes Apps tab). From there, you can save it to your computer. You can do this to backup your profile or send it to someone else. You can also import these files into NewsBrain from the Profiles Screen.
