Karma

From Chiki

Understood by some, used by even few, loved, hated and useless, karma is probably the weirdest thing on the forum (apart from the members). It is the two button under your profile. Exalting raises it, smiting lowers it. You can exalt or smite one person per hour but you can't touch your own karma, unless you're sad and have multiple accounts, which incidentally is also a bannable offence.

Karma sigs

Putting links to your (or anyone else's) karma in your sig is generally not approved of, but hiding the link as something else is banned.
