I have decided to configure my WordPress blog so that users have to be registered and logged in in order to post (by using the admin setting by going to Settings, Discussion, and clicking on "Users must be registered and logged in to comment").

But then I noticed that the blog prompts the user to Log In but does not prompt them to Register. At first I thought that this must have something to do with cookies. Since the server can use cookies to see that I had once registered on my own web site, it would not prompt me to Register again. But after I cleared the cookies, I noticed that it still did not prompt me to Register.

How can I have both "Log In" and "Register" offered on my WordPress blog?
