I still do not see the upvoting radio button.

How do I vote? in the Voting/Experience System says:

If you don't see any vote buttons, that could be because: (a) you can't vote because your monk level doesn't grant you any votes; (b) you've used up all the votes you had; (c) you're viewing something that inherently can't be voted on; (d) you've already voted on all the votable nodes on the page.
