redirect sign in/sign up to page other than home?

Ok thank you. I would prefer not to add buddy press(ive added the plugin before and it doesn’t fit what my design goes for @ baseballscholarships101.com). I really don’t mind the code if I knew where exactly to add it. I thought it was somewhere by the home_url part? I just want them to go to a page other than the home page when they click sign in.

I just tried plugging in the page extension I was trying to get the redirect to go to (/instructors/instructor-login).

I just wasn’t sure what format or what part exactly

case ‘lostpassword’ :
case ‘retrievepassword’ :
if ($http_post) {
$errors = geodir_retrieve_password();
$error_message = isset($errors->errors[‘invalid_email’][0]) ? $errors->errors[‘invalid_email’][0] : ”;
if (!is_wp_error($errors)) {
wp_redirect(home_url() . ‘/?geodir_signup=true&checkemail=confirm’);
exit();
} else {
wp_redirect(home_url() . ‘/?geodir_signup=true&emsg=fw’);
exit();
