Customer user creation and control page

Hi all.

I’m currently developing a theme and I want to have a separate custom page to create users from in the admin back-end.

So for example, if the theme was for a football team, rather than the administrator using the “Users” menu to create new members of the team, he could use my custom “Members” page with custom user fields. I’ve looked a the wp_create_user function and I’m sure this will come into it, but I can’t figure out how to implement this. Hours of googling have yielded no results.

Please help. Thanks
