Customize Activate Page with New Login URL

I am REALLY surprised with all the brute force attack actions by server hosts and all the popular security plugins that change the default wp-login.php page to whatever you want it to be, that more people are not searching for a solution to this issue. REALLY SURPRISED!!!

So, I have a custom “secure” login page now, but when my new Buddypress members Activate their accounts (successfully), the Activate page says:

You can now login with your user name….

And, the link to login is the wp-login.php page! YIKES!

Can someone please send me the code to customize this Activate page with my custom url?

I am not a coder, but I can follow instruction well.

I am on a SERIOUSLY TIGHT DEADLINE, so if anyone can help me ASAP, I would be SOOOO grateful!! ? ??
