1.How do you add spacing to your PSN online ID? Is this article correct? -> http://www.ehow.com/how_8591019_put-space-ps3-username.html

2.Can you use a USB wireless keyboard(or a normal usb keyboard) to chat in-game while playing at the same time with a PS3 controller on a game like metal gear online? Or do I need a PS3 keyboard controller attachment?

3.Is it possible to unlink a PSN account with a PS3 console user account? I accidentally logged in with one of my PSN accounts on my brother's user account and now I can't seem to change it to another PSN account. Anyone know why?

Thanks all!

1. I dont think you can, you may have to use a dash or an underscore.
2. Not sure but i doubt it.
3. Just change the email address and password and you should be good to go.

man i wish i new or i'm just not understanding the way your wording it. well i'll try

3. yes you can. you just have to remember the pass word and email address you created and your on your way.
2. i think so but post on M.U.G.E.N wall sence he has not entered this thread yet for more info
1. if you want to do number 3 on on your list you won't be able to, but if you create a new account you should find out in 2 seconds.

It isn't. He'll have to create a new user and then log in with his PSN account. :|

3. yea you have to create a new account, which is no biggy pretty easy and no content is lost, then delete the old one.

2. You can use corded keyboards and do everything you said but for the wireless dongle ones, maybe, i am sure they work as well.

1. No clue, use underscores if you cant figure it out.
