If I rate someone with 1 star, how do I go back and rerate them with more stars later? Or less stars if I give them more than 1? Can I?

Once you vote thats that; if it was allowed to vote more than once on someone all anyone would need to do is make an account and rate themselves 5 stars 90 times lol..

Well if it remembered what I voted last time and changed that entry, so my vote only counted one time, that would be what I was after. I'm not using a public system anyway, and so far, everybody is getting 5 stars from whoever rates them. I thought I'd be smart and give someone 1 star just to be different, and now I can't go back and change that. Bummer. It was an admin, so maybe they can wipe their slate clean. I turned the rating off on my profile.
