So, you produce some kind of art or media?

I say sharing is fun! 

Check out openclipart.org, jamendo.com, blender-archi.tuxfamily.org, blender-materials.org, they are some places where you can get free (as in freedom) stuff.

Check out blender.org, gimp.org, inkscape.org, they are free tools to make stuff.

Check out  creativecommons.org/licenses/by/3.0, creativecommons.org/licenses/by-sa/3.0, sam.zoy.org/wtfpl, artlibre.org/licence/lal/en, they are tools to make stuff free.

Check out freemedi.googlepages.com/freemedi.odt, freemedi.googlepages.com/freemedi.pdf, they are the paper pages to this web page. 

To be more specific... 

Check out forum.freegamedev.net to find out that the free gaming community needs artists.
