This isn't really so much of a question as it is a heads up. I've added a new forum to my website called SoundSwap. All it's for is trading sound effects and nothing else.
I started thinking about it back when Jay put up this post. While I know Freesound.org is out there, a lot of us can't use sounds from there because of the legal stipulation that we credit the owners of the sounds (and there's no allowance for synchronization unless the sound has been modified). Freesound is a great site, but I thought that a more personal approach might be better for the community.
So, you can trade sound effects that you personally own. Not ones from a library you've bought, but ones you've recorded or synthesized. I have no idea how well the site will work out, but I figured it was worth giving it a shot. If nothing else, it may come in handy for people participating in the monthly challenges I run. ;)
