It is revealed in a recent PlayStation Blog post that there will be some changes to the PlayStation Underground log in system. The Underground system will be dissolved and PSN users will be able to log in to the sites that formerly used the PlayStation Underground system such as the PlayStation Blog using their PSN IDs.
There are now some enhancements to the PSN gamer profile. These enhancements include being able to show your friends list on your profile as well as game ratings and reviews. Sony has also said that there will be more changes to the gamer profile to come before years end. Why not log in now and try it, and see what your friends are doing whilst you’re away from your PS3?
