Okay guys, buckle up because it's just been made even better:
- It is now compulsory to give a reason for your karma change. You *can* leave the box blank, but it's always nice to let 'em know!
- Fixed time limits. Apparently 24 hours doesn't work, so 12 hours it is! If I see someone giving more than one karma per 12 hours (there will be leniency and benefit of the doubt, this is only for abusers), I'll know you've evaded the restriction somehow. Let me give you fair warning, that is knowningly abusing the system, and I'll just strip your ability to use the karma system. Also, if I'm feeling particularly titchy I may also give you 1 billion negative karmas.

- Accountability is here!
You can now view who has changed your karma and whether it was positive/negative and the reason. Simply click your profile and scroll down till you come to "Whose karma have I changed" and "Who changed my karma"
Click either link and you can see stats for who you've karma'ed or been karma'ed by. Also, there are other nifty stats for you to see, like top 'applauded' and 'smited'.
Enjoy!
