Q&A for website

Quite simple. Just create an account on http://www.pubble.co and then set up a community name and create an app name. You can then set up moderators (people who can answer questions for you) You copy the code that they give you, paste it into your page, and your’re all set. Once you publish, then you can see the Q&A running on your WP site.

Features:
Voice search (pretty cool, but only works on Chrome)
Auto Suggest (but you need to have a lot of questions for it to work properly)

Pros and Cons
Great app easy to use and work
Cons – could do with some UI upgrades for some buttons, etc.
