Did I miss this, or did we never actually write the code that would increment / decrement the votes on the Question?

    function(req, res, next){
        if (req.params.dir.search(/^up|down$/) === -1) {
            var err = new Error("Not found - wrong up/down vote string.");
            err.status = 404;
            next(err);
        } else {
            req.vote = req.params.dir;
            // console.log("Vote: "+ req.vote);
            next();
        }
    }, 

    function(req, res, next){
            console.log("Comment"+req.comment.votes);
            // console.log("Question found!");
            req.comment.votes.save(req.vote, function(err, topic){
                if (err) return next(err);
                res.json(topic);
            });

            //problem with voting, look to earlier post requests.

    //      res.json({
    //       response: "You sent me a POST request to /vote-" + req.params.dir,
    //       topicID: req.params.tID,
    //       commentID: req.params.cID,
    //       vote: req.params.dir,
    //   });
    });
