There's a new Jquery Exchange Q&A for Pupunzi | Pupunzi
It was long time that we in Open Lab were thinking to make our own Q&A software. We need it to give support for all of our products, from Teamwork to Licorize. We didn't want to make a Forum because we didn't want structured and complex discussions. Just high quality Questions and Answers. Something like Stack overflow; simple, easy to use, useful. A tool that brings the attention to the more relevant questions in a smart way. Finally we are happy to announce the beta of our Q&A and we decided to use the Pupunzi's one as the guinea pig :-). It is a Java based free and open source project running on Tomcat6+, JDK6+ and MySQL. It has a notification system built in available for all subscribed users; a reputation system used both for questions and users; you can enroll using the most commons openID (Twitter, Google or Facebook) or just creating a local account; it can share each question's threadon Facebook or Twitter; the design is nice, clean and easily customizable. the icing
