Community Auth Redirect

Hi Skunkbad,
I wonder that the function $this->require_min_level(1) will just return true/false or it redirect to login page if false.
I am trying to initial create new user with auth_level =0, then after email verifying is confirmed, it will set auth_level =1.
But I found that just after register new account, it will redirect to page /login. I tried to look for where I could prevent this. So, I can return message telling new register to check email etc.
Please advise.
