Change Register link URL

Hey, Im sure this is a simple fix but I was unable to find anything useful online since Im sure s2members is stopping me from doing this.

I am trying to change the url of the register anchor at the bottom of the login fragment. The reason being is I am using a different register form plugin so I can use a shortcode in a page, and I havent been able to figure out how to do that without using an iframe in s2members.

Any help in the right direction is appreciated.
