''New user registration on your site'' how they register on my blog ?

Dear WordPress Community,

I have been wondering, where the users registered on my web site ?

I receive many emails from wordpress saying: ”New user registration on your site Bali Radar:

Username: **************

E-mail: **************
”

All in all, I know it’s a good sign but I have been searching to know where or how they subscribe on my web site.

I know that is because in my WordPress Dashboard Admin/Settings/General under Membership I have ticked the box entitled “Anyone can register” and my option “New User Default Role” is set to “Subscriber” BUT I still don’t know how they register.

On this topic : http://wordpress.org/support/topic/new-user-registration-on-your-blog-aaaaa-what-does-it-mean

esmi answered : ”they registered on your blog – possibly by accessing the registration link directly.”

I searched in the wordpress documentation for the keyword ”wp register” and found : ”This tag displays either the “Site Admin” link if the user is logged in or “Register” link if the user is not logged in.”

When I’m not logged I see no way to register. I would appreciate to know how they subscribe on my website ?
