Hi Lulu
Part of the karma rating is calculated by other people's activity.
For instance if one member was to be more active, send more PMs or chat in the chat room, their karma rating would increase and someone else's would decrease if they hadn't done anything different. Perhaps the same works the other way?
I'm sure Matt will correct me if I'm incorrect.
I've said it before and I will repeat myself I think 'karma' is the wrong description, I think it should be called 'activity' cos that is what it's based on.
It's not so much about popularity as activity.
Some competitive members seem to get their knickers in a knot about it when their karma goes down, as if it's their popularity that's being decreased.
Dictionary definition of the word karma:
the sum of a person's actions in previous states of existence, viewed as deciding his or her fate in future existences
and as Matt won't allow us more than one profile then we can't have karma
