I was thinking. Xfire is growing quite big, and Im fairly sure quite some people here have it. Why not add it to the contact data, since SteamID is on there aswell?
One of the first ideas I bandwagon into in months. Since Xfire is waaaay more poopular than STEEEEEEEAAAAAM...... it should be able to be added to the list. We need to do SOMETHING to that free space right?
Also: Xfire raises awareness for many flash sites and underground games. Log unto AG whilst on Xfire and you rack up hours to show your support and show everyone how active you are on the site. You can do many other things, such as join someone's multiplayer game.
Plus it would increase standings between people. If we add each other, we know each other, we offend each other less and we have less troubles. We might even be able to help more newbies this way, if they add their xfires :P
But ok, I'm far ahead now. It's just a small thing, but it would be nice to have, and like freaken said, Steam is popular, but not for contacting at all. Xfire is much more supported.
