No I'm not rating this site for Resources or Amount and Quality of Material because it's an interactive site with resources and material changing quickly. This is Francis Ford Coppola's free Virtual Studio. As of this writing there are 18,124 participants with 64 joining this day. It's not an informational site from the standpoint of being a link to hundreds of contests, articles, how-to's and producers. Instead, its information comes from the interaction between members.
Screenplays uploaded to the site receive feedback from as few as three people to over twenty.
Reviews can be an eye-opener for anyone who has not received feedback on a script before. Uploads are not made public to anyone other than members of the site. I've belonged to this site since Spring of 1999 and often learn more here about the prevailing winds in Hollywood than anywhere else. Any industry news from script standards to word on possible strikes is analyzed thoroughly by members. If someone has a question all they do is post it and they will receive multiple answers.
