It appears as though that the official PlayStation forums (us.playstation.com) has started linking PSN ID’s to your forum user/login ID.
You can even view your PSN friends list on the forums. This is an excellent way to kick off E3.

ID Linking FAQ
The free service from PlayStation® that allows you access to Online Gaming and the PLAYSTATION®Store. It also gives you a variety of ways to communicate with your friends.
It’s not a problem; register your online ID today!
Once you’ve linked your IDs, you’ll receive all these great features:
To link a PLAYSTATION®Network ID, choose a destination according to your current membership:
I have a PLAYSTATION®Network ID and want to link it.
or
I need to get a PLAYSTATION®Network account.
Yes, you will need to have a PlayStation Underground account in order to access your PLAYSTATION®Network features on the Web.
It’s not a problem; however, certain features of the PLAYSTATION®Network require a PLAYSTATION 3—specifically, choosing an Avatar, managing your Friend List and editing your “About Me” message are PLAYSTATION 3 specific.
Your ID is your PLAYSTATION®Network name that you pick when you sign up.
It’s visible on your portable ID, on all PlayStation message boards (including any social networking sites where you post your portable ID), and on your buddies’ Friend Lists (where others have you listed as their friend). It’s your identity everywhere you go within the PlayStation online universe—and in some cases, outside that universe as well. Anyone who sees your portable ID or visits a website where you’ve used your online ID will know you by that name, which is why it’s imperative you pick a good one! Remember, once your ID is set, you can’t change it.
“About Me” is a snippet that tells other players a bit about yourself, your favorite game or what you like to do.
You will be able to see your PLAYSTATION®Network friends and view their online status, but you will not be able to manage your Friend List. You can access the Friend List on your Account page within the PlayStation Underground.
It is a visual summary of your PLAYSTATION®Network account, including your Avatar, “About Me” message and Online ID. You can get a link code to place your portable ID on message boards and other sites by clicking here.
Only accounts that have logged in on a PLAYSTATION 3 console can be added as a “friend” at this time.
Online Status shows if you or a buddy are currently online (blue), online but away (yellow), offline (red) or pending friend status (gray).
If a user is online, their comment will be displayed (you can change your comment) on your PLAYSTATION 3 console:
If a user is offline, the last time they were online will be displayed as “Last online XX hours XX minutes ago”
If a friend is pending, then it will say, “Friend Request.” If the user has sent you a Friend Request but you have not yet accepted, it will say “Pending Friend Request.”
To accept a “Friend Request,” you will need to log in to the PLAYSTATION®Network on your PLAYSTATION 3 console:
the link to “link” the psn id’s don’t work!! or is it just me!!?
Thanks for bringing that up.
No its not working for a lot of people.
I think the feature wasnt fully ready. Give it a little time.
The good news is that the feature is pretty much ready to roll out.
And what a great feature it it!!
Yup. I’m getting the ol’ 403 Forbidden Error.
Try using Internet Explorer. I tried firefox at first, wasn’t working until I switched to IE.
waiiit i found out how its suppose to work!!!!
you need to have a playstation underground id to access the linking!!!
i just did it right now!!

awesome stuff guys!
thanks for the heads up, i just linked mine now. maybe we could get this API running on this site as well. that would be cool.
can’t wait to see your live E3 coverage tmrw!
how do i view my friends list on my computer? i cant access anything
Link wasn’t working for me either. But then I just went to the log in on the main site and a Link Account option was right next to me name afterwards.
Kinda sweet. Seems a bit flaky atm though. I was able to link accounts, saw PSN right next to my GAP button. But when I click on the PSN it always asks me to link accounts or log in with a linked acount to get html or anything. Clicking the link asks for my log on name/pass and then drops me back at the PID page asking to either link or log on.
Just a loop of that so far.
This is very cool and a step in the right direction.
I tried on Firefox and nothing happened but on IE i got this:
“There was an error trying to authenticate you.
Please try again.”
Does anyone else?
Not working for me neither.
Has it be a US PSN ID, or can it be any PSN ID? Can you write me some State, Province and Postal Code? I´m from EU but i want this feature! Thank ya all.
Ok, the link was wrong thats why it was not working. After logging in to ur underground account, go to here : – http://www.us.playstation.com/Registration/PSNL
Nice idea.I need to remember my freaking password for the underground though.
This is a very nice addition, I cannot wait to see what more they can do with this.
After linking your account, I suggest you log out then back in to your PSU account. This will often fix any problems you were encountering.
Somebody from EU, who has already this feature working with his PSN ID? Somebody pls write me some state, province, postal code. THX.
Great! Thanks for the heads up
Veks: They did link the PSN ID in Europe a few months ago. You didn’t need anything special other than your actual PSN ID and password.
Did it even if I’m in N.A. and had no problems whatsoever. Not sure why it is so complicated with the N.A. forums. Though, in Europe, they didn’t link it with your friend list and so on…
Real: Thx for your answer. I have my PSN ID linked with EU forums, but as you´ve said, they didn´t link it with my friend list
And i really want this feature. Then…
Anybody with EU PSN ID, who has already linked it with US PSU?
I’m having problems updating my About Me section. Any help?
Get your Portable ID!
