Can I make my mouse auto click?

Hey I was just wondering if any of you have heard of a program that u can use to set your mouse to click every few seconds while u or at work or whatever. You see my problem is that I want to register for this course thats really hard to get into, but my only chance is if I spend my days clicking the "add course button". Anywho, Can anyone help my chances? I want it to click every 10 secs so when someone drops the course, bam! Ill get in. Thanks in advance

Wow, I'd be careful doing this.
Some people get in trouble for doing things like these.
Anyways:

If you think 29 days is good enough, try this (30 day trial):
