In order to use permissions fully, people should not be able to make themselves members of sites by just clicking a button. only an admin should be able to do it.
Because of this, a member just joins the site and gains reader privileges. I dont neccesarily want to hide the site completely but may want to hide some folders/files if a user is not part of the site's members.
Also the invitation button is just likely to confuse users. I mean whats the point of joining you could say? Since you can just do it yourself the permissions for selfjoined members and others must be the same….
How can I do this?
