Excellent site, but I have a problem. I'm getting undervote notices, and I don't know what they refer to. I'd like to vote; I want to vote; but, I have no idea how to vote. . . Oh, the humanity! Can someone tell me what's going on?
As long as you are a member (and you must be, if you are posting here) you should see a drop down box to the right of the preveiw image with the "Vote" button next to it. Just select the appropriate number from the box and click the button.
