Question regarding Tournament Registration

Hi all Newbie here,
I did a search and could find the answer to this question so maybe some one can help me. Is there any kind of program that will let you automatically register for a tournament on Pokerstars once the option opens up?

On the "Daily 80 Grand Freeroll Satellite" once the registration button comes up I click it to register and within seconds there are 2000 people already registered. Seriously, How can they register so fast? Just wondering how they do it so fast.
