I wonder if anyone might be able to assist me... I want to design a website that will have a type of rating system that will allow users to rate a particular items.......similar to the ebay style of postive/negative comments and ratings (i am sure you know what i mean) but I really am not too sure of where I would start or how to do it.

If anyone could point me in the right direction (programs to use, tutorials, ideas....etc) then I would really appreciate it

Many Thanks
