I've been on websites very similar (Such as
Backstage
) to this one and they have actul acting, not just voice. This is called "Casting call club" meaning it should be open for other forms of acting as well. Limiting it to audio stuff, and animation only is limiting your users. I started as a voice actor, but moving to filmaking in general. So yes, sound is important, but we need people on camera, and people behind the camera. Location can be optional since I know some people wont be willing to give that out at all, but if their looking to actuly be on a set this can be a good place to start.
