New registration and login forms

I use a Buddypress registration form at the link mysite.com/register and I realized today that GD is redirecting logins and signups to /gd-login. On my Buddypress registration form I have integrated a newsletter signup option and other fields that I would like to keep. Also, I’m using a spam registration blocker that works with WordPress forms and Buddypress forms, but not GD.

When unlogged users try to add a listing, is there any way to forward them to my Buddypress registration page instead of GD?

Thanks
