Okay i've been working on my new site:
http://lockpick.lukeidiot.com/?go=apply

And I have the Job Application pretty much done, except I want it to be a little more secure. Is it possible to limit the number of 'Submits' a user from a certain IP is capible of submitting a Job Application? (example: user1 from ip: 127.0.0.1 sends in a Job Application Form, and is only allowed one submit per day/week/year) Is this possible?

AKA One submit per IP, per time limit?

Thanks,
Lukeidiot.
