1 per day sounds good (as long as count does not accumulate)

1 vote per member per day.

To make it work you have to think of the offender?
What i mean by that is if someone wanted to abuse the system,
then having only 1 vote per day isn't going to spoil it for the many.

The point being that we only want to use the rate feature
to be vindictive or genuine praise currently. where it should
reflect to others the current feelings from other members about
that member. if that can not be achieved then why have it
switched on at all?

Obviously i havent thought far enough ahead about the algorithm
and how that would work, but for me 1 vote per day lets you
change your feeling towards members.

Lets face it,
you don't get more than on member wanting you to rate them 1 at the same time lol.

Feedback ??

Did anything ever come of this?

I have a user that rated someone a 1 instead of a 5 by mistake and wants me to change it. Must I dive into the database?
