incomplete conversations of people trying to implement something. The
first one is filled with text errors (so it seems anyway) so I'm
having a big difficulty getting it working. Does anyone know of more
recent information on using acts_as_rated or acts_as_rateable doing an
Ajax submission similar to those above?

Much thanks,

working assistance to show how to do this. For those of you that are
curious too on how to do this perhaps you wouldn't mind voting up at

maybe Ryan and RailsCasts might cover something.
