Voting on Posts Request

[JBMoney]

I have a small Photoshop forum and I'd like to find something that would allow folks to vote on individual posts within a thread. I could see two possible ways to do this, either of which would work for me.

1) Vote for ONLY one (or another predetermined number) post out of the entire thread.
2) Apply a rating to each post within the thread.

There's usually more than ten submissions, so I don't think creating a poll and merging threads would work to well.

It might also be nice if the feature could be restricted to groups as the current polls are.

Is there already something like this available?

Thanks.

JB
