Using Register Plus - How to activate on wpmu

Hi there,

I am having problems getting Register Plus to work and I would really like to beable to add extra fields upon sign-up.

I have installed Blog registrations as well http://wpmudev.org/project/wpmu-blog-registrations

I am trying to access the register plus page with http://schoolcommunicationarts.com/wp-login.php?action=register

but keep getting redirected to standard sign up page.

I can see that it does work as with this user https://premium.wpmudev.org/forums/topic/user-defaults#post-13917

But im not sure if I am supposed to alter any code to make this happen.

Thanks in advance for any help
