We recently released a new feature to our Pro Members called the Casting Board. The board is a great list of updated castings that our members can submit directly to (and there's no restriction to how many you can submit).
 
The board also includes print, theater, film, and misc opportunities that don't get featured on our main pages. We currently have over 100 open casting calls and we're going to be updating it constantly. 
 
If you get a second, check it out:
