Reputation, how to...

[OTWA]

I currently have the reputation setup so that only usergroup 6 can use it.

When I click on the "leave reputation" option, the window pops up and allows me to enter a comment, and select positive or neg.. (the default reputation given is pulled form the ACP, 'How many reputation points does an administrator give or take away with each click'?)

I want to be able to input the # of points directly in that popup. The idea is this...

existing field --> positive or negative (radio buttons)
existing field --> comment (text input)
want to add new field --> # of points to give (#/text input)

I looked around a little bit and didn't find anything useful.. Can someone help out? What files and values do I need to change?

Thanks,
-Jim
