[geeklog-users] removing new user joining link

[geeklog-users-admin]

I have been trying to remove the "Don't have an account yet? Sign up as a New User" text and link from the "User Functions" block. I don't want just anyone signing up to gain access but I do still need the login part of the block. What is the file I need to edit to remove it? I will add users manually under admin as needed to have total control over who gets access so I will never use this link. Thanks in advance.
