Member sign up not activated

I have BP and MUWP and I click on sign up now and it doesn't go anywhere.
How do I do this? I figured the Daily Theme would already have it set up. I think I may just have to link it up I just don't know where I go to do that? I type in Mysite.com/register and it's their I just don't know where that link where it needs to go. I copied this from the Manual! LOL! Thanks for your help.

"You need to create a link to your signup page from the front page of your main site so people know where they can register for a username on your network by either:

1.Using a theme that includes an option to add a link to your signup page
2.Adding a link to your signup page
3.Using an admin bar that includes a link to sign up for a site
By default, your signup page is located at http://example.com/wp-signup.php"
