I don't know that we have "free" resources here, such as you have in mind. We are more a place for people who need psychological help and support for their problems and people who are a point in their ailments where they can help. However, there is a site for students who are interested in psychology. It's listed at the very bottom of the first page of this forum. As far as I know, it's an active group.

I am glad to hear of your interest in psychology. I am a social psychologist.
