Enable logged out voting for Q&A


My client would like for users to be able to vote for questions when they are logged out. I've read another support issue for this same topic, and the plugin developer responded that it is intentional for users to be required to login to vote. However, we are fine with that users will be able to vote multiple times, as currently, no one is voting because it's not worth it to them to create an account to vote on a question.

How can we enable voting for non-logged in visitors?
