Disable component registration

We have Easyblog, EasyDiscuss and EasySocial all working together in harmony. Along with several other big programs. Cool. But it seems like everybody includes registration as an option. But this isn't always good because often we route all registrations through a third-party membership component. We can't have all these disparate registration points. At the new huntingplanit.com, its' really an issue with one click which can be seen here: https://huntingplanit.com/social-network-frontpage. It is what non-registered users see when they try to enter the social network from the public front end. At right on that page is button that says Register Now! But the click leads to nowhere - just a message saying "Sorry, but there are no profiles created on the site yet." I would like to either delete that button or direct it to our centralized registration page. Delete is preferred.
Sorry that I couldn't find a similar case in searching the forum.
I am capable of making the php edits if you just show me where and what.
Thanks!
