Yep, this is it. UNDER DRIVE REGISTRATION.
Registration for each robot is $50. Registration form and the rules can be found on the link on the flier. Look on the menu bar, under UnderDrive 2008.
Have fun. 
What is UnderDrive? What flier? What link? Do you have other information?
The one (originally) linked badly & now just reproduced here:

Yep, UnderDrive Registration is now open. Rules and registration can be found at the link in the form. Just go to UnderDrive 2008 on the menu bar.
The cost is $50 per robot and the rules and restrictions are EXTREMELY slim.
If anybody was as confused as I was, I think this is the link to which he was referring.
Too bad it is in Georgia, or I would have built a robot for it. 
OH, wow, sorry, here is the actual flyer.

This game is simply a scaled down version of OverDrive. We use a 1/3 scale to scale almost everything down to size. Of course there are some aspects which could not be scaled, ie, ball, ball weight, but the right size ball, 13" in diameter, has been chosen so that it would extend beyond the chassis.
the true link is, http://prhsrobotics.com/team/content/view/33/49/ , Here you will find rules and sign up information.
Hi all,
Apologies for bringing up this old thread. Anyone who’s planning on attending should know this already, but just a reminder if anyone still hasn’t figured it out:
What: 1/3 scale version of last FRC, Overdrive. All robot systems allowed (although we’ll be using VEX).
Price: FREE! Yay! It’s our first year, that means no guarantees 
Feel free to drop by and check it out.
When: THIS Saturday, Nov. 22nd, 2008.
Where: Peachtree Ridge High School
Doors open at 9:30
Inspection/Practice runs 9:30 to 11
Seeding 11 to 3
Finals 3 to 4
Awards 4 to 5
We have some awesome trophies courtesy of our mentor and some scrap parts.
Reminder again that we’re running this on linoleum (no carpet), size restrictions apply but no weight nor money restrictions at all. Matches are run 2x2. Inspection is basically just to make sure your robot isn’t dangerous, they’re be an Inspection Station and our head mentor will be there. Tape and glue not allowed. And our head mentor may override any and all rules.
Order forms for lunch when you get there, you’ll need to schedule your lunch in between matches somehow, since we’re running a tight schedule. It’ll run ~11 to 1 pm. Snacks sold 10 to 3 pm.
Oh yes, there’s a flag we’ll give you to put on your robot, but it’s small and easy to put on. Shouldn’t be any problem.
Oh, and you’ll be subject to being photographed and videotaped, we don’t have consent forms but just let us know and we can photoshop if needed, hehe.
For some idea of the field/ball, go here:

Those are old pictures. We have plexiglass and paint now! Whee!
Good luck tomorrow everyone! Wish us luck working all the logistics out
