I'm using Drupal 6.
I want to redirect users from /user/login, /user/register, /user to /sign-up if the user is the anonymous user. This page would show both login and register forms together.
The only page left would be /user/password, which form I don't want to have on /sign-up.
I'm comfortable with PHP, but I'm not sure about which hooks should I use to achieve this.
PS. I already know how to print those forms on my own. My doubt is just about the URLs.
