i want to do a rating system like youtube's where it averages out the total ratings. i'd store each of the ratings per each row and have them seperated by comma's then in my code put them in to an array.
i also wanted to store the usernames of the voters in the database in the same fashion (without displaying them though) as above say instead of using cookies (as they can be deleted). would method this be feasible? or would this say overload the database and cause slow down?
