SOME of my krama hack features would include (ruff type up)
-full CP features (ie. features below editable via CP)
-admins set a vote flooding (ie. user can only give karma ot a user, once a day, once a week, once a month)
-all users start at 0 karma, one GOOD karma gives them +1 one BAD karma gives them -1
-users gain a CP set number of +karma when they hit posting marks (ie. user is at +5 karma, he hits his 100 post, he gets +5 karma
-karma reset (ie. set all karma on users to reset after 1,5,12 month(s) or never
-users can't give karma until set number of posts (ie. new users can't give karma until they hit 10 posts, or from when they join)
-when mods, or admins give karma it counts for more (ie. you can set your mods to give +2 or -2 karma when normal users would be +1 or -1)
so many other features, most number ones are editable from CP, I don't have time to type them all out, cuz I gotta do some lawn work
