How could I add a reputation log
 

I'd like to have a reputation log so that users can see who gave them rep and the date. Sort of like the default in the User CP but so they can see all rep given not just the latest. Thank you.

You can increase the size it displays under user reputation options. While you can't make it everything, you should be able to make it large enough to pretty much always display all.

Admin CP -> vB Options -> User Reputation Settings

Thank you but that is what I am already doing and it's okay but I want something similar to the Reputation Report mod and havent found anything like this yet.

//EDIT//
I set it to display 1000. Is that too high of a number? Will I notice server strains? I set it to this b/c no user will possibly obtain 1000 rep any time soon. Thank you.
