Can answers to forum posts be up voted or down voted?

Is there any opportunity to vote / rate answers?
Users should be able to vote on comments so that others see immediately the highest voted answer, which most likely is the most useful answer.

It's always worth starting by searching the addons section by relevant key words.
Thanks! I run a quick search but obviously did not fine current topics. I just found a plugin and a forum post from 2010 or 2011.
No problem. For plugins, rather than search the forum, go to the addons section, and then use a relevant keyword.
