in reply to enabling "Submit" button after X seconds.

Robots work by filling out every field on a form. I learned the trick of hiding (using CSS) a text field with an innocuous name and then validating it on the Perl side of things. If the field contains a value, I reject it.

If you did want to create a delay, it is possible to use javascript and jQuery, but that's too OT for the Monastery.
