I turned off the notifications. It was pretty simple. I wonder what other features are "hidden" in the PS3 options.......
I guess I'll just pull my ethernet cable when I want to remain anonymous. Making an alt account isn't really an option. Every now and then, I stumble across a trophy. I'm not a trophy whore by any means but I like credit for what I earn.
I work with a bunch of guys who LOVE the PS3. All of them make it a mission to be on each other's friends lists. But, they only play "manly games" (MW2, Madden, NBA Live, God of War). It's just this one guy that tries to play games like Uncharted 2 or Batman that gets on my nerves!! Can't delete him, though. I just hate his "mooching" off of me.
Once again, thanks for the replies!
