As it was if you voted for a post you then wouldn't be allowed to change your mind which I thought was a little sucky so I've set it up so people can vote for a post but can change their mind at a later date if they wish.
eg if I give good karma to a post then the person who wrote the post pisses me off I can go back and remove the karma. After that point you can no longer vote for the post.
No, no, no!!! This goes against the whole purpose and principle of such a system. You are supposed to vote for the post and the post's contents and it's contex in the given thread. You don't vote for people you like and dislike and you shouldn't be allowed to go back to change your mind and do this.
Go and hang out at slashdot, or perlmonks.org for a few days, even weeks to see what I mean!
