I'd like my users to be able to select topics to go in a "My Page" type view, or "My Site" that they can invite their friends to in order to view their site and nodes of interest. Any ideas how to do this? One idea is to give each user a book (is there a way they can control their own book but not others?) where they can use the "edit book outline" feature to add nodes of interest to their book. I'm not sure if this would work and if each user can have their own book that only they access, but it is a thought. Let me know your thoughts on the topic. thanks.
