Valve looking for user-created items in Team Fortress 2

There once was a time when your only option for exercising creativity in Team Fortress 2 was to come up with clever ways to grief your fellow players. Today, Valve announced that players would soon have a less annoying way to stretch their imagination muscles -- by designing their own items and avatars which could possibly show up in-game.

Of course, you can't simply break one of the classes by creating a mini-nuke launcher for them -- there's a number of restrictions to what's appropriate for the game. Check out Valve's handy "Tips and Tricks" page to find out how to ensure your homebrewed creations are TF2-acceptable. For instance, a new fedora for the Sniper? Absolutely. A gun shaped like genitalia for the Heavy? Absolutely not.
