Can someone recommend a php mysql rating system that I can add to my site

I'm looking for a php/mysql-based rating and comment system that has a one time license fee per site. Can someone recommend something?

I could build my own -- I already started but then I was thinking there must be something out there already.

It would be nice if it included the abil开发者_运维问答ity to poll people too.

Thanks

I've been seeing a lot of sites using Disqus. You might give that a look.

It's not really clear what you need exactly, but facebook is offering comments for your site as well.

you could build your own threaded comment system with this class here:

You would just have to design your table structure, its not really that hard, as for polling would be something else, i dont think you'll find an integrated soultion since, they are two different beasts.
