Communities Plugin- How do you get shortcodes to work, in particular, the Post Voting one?

Hello again! I'm trying to get a shortcode to work within the Communities plugin- in particular, putting the Post Voting plugin's shortcode into a messageboard post. I'm sure in the future there will be other shortcodes that users would want to put into the messageboards and whatnot also.

How does one go about making this work if shortcode functionality is not going to be in an update soon?
