I _don't_ think ot would be nice. That way you would have to reload the entire page every time you vote. That would take a lot of extra time when you want to vote more than once in one thread. What I would like, is a way to deselect a certain vote. You select a vote, then decide you don't want to vote to that, but to something else in the thread, while you already selected several other votes. The only way to deselect a vote now is to reload the page and enter all your votes again...
All Camels are equal, but some Camels are more equal than others.
