Thanks John. I am using Drupal 6.2.

I am sure what you say will work, and I will be able to change
validate handler though form_alter, and validate hook will be called
before user is deleted. Only problem I guess is that: it will be
called only once even if multiple users are being deleted ('coz it's
form validate handler, not user delete handler). Right?

If possible, I wanted my validate function to be called for individual
user, and delete/not delete user based on errors returned by validate
hook.

Thanks,
