Can I disable forum registration & login?

Hi, thinking of buying your forum software to integrate into my existing asp.net website. I use asp:membership with sql server and would want to use single sign on (which seems straightforward having read your instructions).
 
However, I would only want users to be able to register and login via the asp:membership system on the existing site, i.e. is it possible to disable any registration and login links on the forum? I would ideally redirect the user to the existing asp:membership login page if they try to use a forum feature that requiresthem to login.
 
Thanks,
 
Justin
