Create Team Fortress 2 Weapons and Hats!

I heard about this on a podcast a couple of weeks ago (I think it was the PC Gamer Podcast, but don't quote me on that).  And I was blown away.  The guys at Valve have done it again.  They are constantly doing things to Team Fortress 2 to spice it up.  On top of the Steam Achievements, they have added all of those random weapon drops to the game.  Which include better weapons for about every class in the game.  Then they started giving us hats to replace the original headwear on the game models.  So, what next?

How about letting us design our own weapons, hats, and avatars.  Valve said 'Sure'.  So check it out: http://www.teamfortress.com/contribute/.  That's right, pretty cool.  According to their site, the submitted weapons will be for the model only. The game's devs will then work the model into the game in way 'that makes sense' to help keep the game balanced.  They also have posted the requirements for submitting an item to the for approval. 

Keep up the great work Valve!
