suggeston on voting button and vote system
if you can make it float to the right and when scroll it scroll with the question that will be the best soultion
postion fixed after scroll using jquery then un fixed when scroll hits the answer div then answer vote will be position:fixed
if not
why not after the question and under the avatar its easy i think every rating and sharing plugin does this 😀
any way thats my opinion
Thanks shady for suggesting, I am trying all combinations
