The problem with castnet is that you have to 'qualify' to be on their books. I did a degree in drama and have had numerous theatre and film credits but they would not take me on. I sent my cv and professional headshots as requested but they said I was not up to their standard! I have enough experience to consider myself to be an actress. I think you have to be an equity member or have an agent already for them to consider u. I even sent them a reference from a very well known director I worked with but they still said no!
