How Do I Redirect an URL that includes username?

I am using a membership plugin called WP eMember but they have a terrible registration/profile form so I am using the BuddyPress form instead. I also need the members to be searchable.

Here is my dilemma. The eMember registration goes through perfectly but then the email tells them to Login:

Please login to the member area at the following URL:
https://christiangays.com/member-login/

Instead, I want them to complete the BuddyPress Registration/Profile form - it has required fields, and I don’t want them to be able to login until the profile fields are filled in.

I would prefer that the login URL went to

https://christiangays.com/members/username/profile/edit/group/1/

That is the edit page for BuddyPress profile.

How do I do this?

Thank you!
