Hey there,

For registration, you are able to do that by clicking EasyBlog > Settings > General > Users > Login Provider, choose EasySocial, when User press Register in EasyBlog, it will redirect to EasySocial's registration instead of EasyBlog.

Unfortunately, it is impossible for login in EasyBlog as when user who is unregistered or not log in yet use EasyBlog composer, it still will redirect to EasyBlog's login instead of EasySocial's login. We will do something about it in the next version.
