Post your PSN ID and (or) Xbox live Gamertags

This should be combined with the Wii/DS thread (and throw in Steam IDs too) so we can have one post per person like this:

PlayStation Network ID
Xbox Live Gamertag
Steam ID
List of Wii Codes
List of DS Codes

Or Heck, if we can have them as options to fill in on our profile page, that would be even better. This should be able to be done either manually or with a pre-made mod (if you want it to look pretty and show Achievements or Trophies).
